+ ATC260x series PMICs integrates Audio Codec, Power Management, RTC, IR
+ and GPIO controller blocks. Currently only the PM related functionalities
+ (i.e. regulators and system power-off/reboot) for the ATC2603C and ATC2609A
+ chip variants are supported.
+ ATC2603C includes 3 programmable DC-DC converters, 9 programmable LDO
+ regulators and 1 fixed LDO regulator.
+ ATC2609A includes 5 programmable DC-DC converters and 10 programmable LDO
+ regulators.

+ vin-ldo11-supply: Input supply for LDO11.
+
+ Optional sub nodes for regulators:
+ ---------------------------------
+ The subnodes name is the name of regulator and it must be one of:
+ sd[0-6], ldo[0-7], ldo[9-11]
+
+ Each sub-node should contain the constraints and initialization
+ information for that regulator. See regulator.txt for a description
+ of standard properties for these sub-nodes.
+ Additional optional custom properties are listed below.
+ ams,ext-control: External control of the rail. The option of
+ this properties will tell which external input is
+ controlling this rail. Valid values are 0, 1, 2 ad 3.
+ 0: There is no external control of this rail.
+ 1: Rail is controlled by ENABLE1 input pin.
+ 2: Rail is controlled by ENABLE2 input pin.
+ 3: Rail is controlled by ENABLE3 input pin.
+ Missing this property on DT will be assume as no
+ external control. The external control pin macros
+ are defined @dt-bindings/mfd/as3722.h
+
+ ams,enable-tracking: Enable tracking with SD1, only supported
+ by LDO3.
+
+Power-off:
+=========
+AS3722 supports the system power off by turning off all its rails.
+The device node should have the following properties to enable this
+functionality
+ams,system-power-controller: Boolean, to enable the power off functionality
+ through this device.
+
+Example:
+--------

+title: Aspeed Low Pin Count (LPC) Bus Controller
+
+maintainers:
+ - Andrew Jeffery <andrew@aj.id.au>
+ - Chia-Wei Wang <chiawei_wang@aspeedtech.com>
+
+description:
+ The LPC bus is a means to bridge a host CPU to a number of low-bandwidth
+ peripheral devices, replacing the use of the ISA bus in the age of PCI[0]. The
+ primary use case of the Aspeed LPC controller is as a slave on the bus
+ (typically in a Baseboard Management Controller SoC), but under certain
+ conditions it can also take the role of bus master.
+
+ The LPC controller is represented as a multi-function device to account for the
+ mix of functionality, which includes, but is not limited to
+
+ * An IPMI Block Transfer[2] Controller
+
+ * An LPC Host Interface Controller manages functions exposed to the host such
+ as LPC firmware hub cycles, configuration of the LPC-to-AHB mapping, UART
+ management and bus snoop configuration.
+
+ * A set of SuperIO[3] scratch registers enabling implementation of e.g. custom
+ hardware management protocols for handover between the host and baseboard
+ management controller.
+
+ Additionally the state of the LPC controller influences the pinmux
+ configuration, therefore the host portion of the controller is exposed as a
+ syscon as a means to arbitrate access.

+* Device tree bindings for Atmel SMC (Static Memory Controller)
+
+The SMC registers are used to configure Atmel EBI (External Bus Interface)
+to interface with standard memory devices (NAND, NOR, SRAM or specialized
+devices like FPGAs).
+
+Required properties:
+- compatible: Should be one of the following
+ "atmel,at91sam9260-smc", "syscon"
+ "atmel,sama5d3-smc", "syscon"
+ "atmel,sama5d2-smc", "syscon"
+ "microchip,sam9x60-smc", "syscon"
+ "microchip,sam9x7-smc", "atmel,at91sam9260-smc", "syscon"
+- reg: Contains offset/length value of the SMC memory
+ region.
+
+Example:
+
+smc: smc@ffffc000 {
+ compatible = "atmel,sama5d3-smc", "syscon";
+ reg = <0xffffc000 0x1000>;
+};

+KEYMILE bfticu Chassis Management FPGA
+
+The bfticu is a multifunction device that manages the whole chassis.
+Its main functionality is to collect IRQs from the whole chassis and signals
+them to a single controller.
+
+Required properties:
+- compatible: "keymile,bfticu"
+- interrupt-controller: the bfticu FPGA is an interrupt controller
+- interrupts: the main IRQ line to signal the collected IRQs
+- #interrupt-cells : is 2 and their usage is compliant to the 2 cells variant
+ of Documentation/devicetree/bindings/interrupt-controller/interrupts.txt
+- reg: access on the parent local bus (chip select, offset in chip select, size)
+
+Example:
+
+ chassis-mgmt@3,0 {
+ compatible = "keymile,bfticu";
+ interrupt-controller;
+ #interrupt-cells = <2>;
+ reg = <3 0 0x100>;
+ interrupt-parent = <&mpic>;
+ interrupts = <6 1 0 0>;

+* Dialog DA9055 Power Management Integrated Circuit (PMIC)
+
+DA9055 consists of a large and varied group of sub-devices (I2C Only):
+
+Device Supply Names Description
+------ ------------ -----------
+da9055-gpio : : GPIOs
+da9055-regulator : : Regulators
+da9055-onkey : : On key
+da9055-rtc : : RTC
+da9055-hwmon : : ADC
+da9055-watchdog : : Watchdog
+
+The CODEC device in DA9055 has a separate, configurable I2C address and so
+is instantiated separately from the PMIC.
+
+For details on accompanying CODEC I2C device, see the following:
+Documentation/devicetree/bindings/sound/trivial-codec.yaml
+
+======
+
+Required properties:
+- compatible : Should be "dlg,da9055-pmic"
+- reg: Specifies the I2C slave address (defaults to 0x5a but can be modified)
+- interrupts: IRQ line info for da9055 chip.
+- interrupt-controller: da9055 has internal IRQs (has own IRQ domain).
+- #interrupt-cells: Should be 1, is the local IRQ number for da9055.
+
+Sub-nodes:
+- regulators : Contain the regulator nodes. The DA9055 regulators are
+ bound using their names as listed below:
+
+ buck1 : regulator BUCK1
+ buck2 : regulator BUCK2
+ ldo1 : regulator LDO1
+ ldo2 : regulator LDO2
+ ldo3 : regulator LDO3
+ ldo4 : regulator LDO4
+ ldo5 : regulator LDO5
+ ldo6 : regulator LDO6
+
+ The bindings details of individual regulator device can be found in:
+ Documentation/devicetree/bindings/regulator/regulator.txt
+
+
+Example:
+
+ pmic: da9055-pmic@5a {
+ compatible = "dlg,da9055-pmic";
+ reg = <0x5a>;
+ interrupt-parent = <&intc>;
+ interrupts = <5 IRQ_TYPE_LEVEL_LOW>;
+ interrupt-controller;
+ #interrupt-cells = <1>;
+

+ For device-tree bindings of other sub-modules refer to the binding documents
+ under the respective sub-system directories.
+ Using regulator-{uv,ov}-{warn,error,protection}-microvolt requires special
+ handling: First, when GP_FB2 is used, it must be ensured that there is no
+ moment where all voltage monitors are disabled. Next, as da9063 only supports
+ UV *and* OV monitoring, both must be set to the same severity and value
+ (0: disable, 1: enable).

+ The Flexible Power Sequencer (FPS) allows each regulator to power up
+ under hardware or software control. Additionally, each regulator can
+ power on independently or among a group of other regulators with an
+ adjustable power-up and power-down delays (sequencing). GPIO1, GPIO2,
+ and GPIO3 can be programmed to be part of a sequence allowing external
+ regulators to be sequenced along with internal regulators. 32KHz clock
+ can be programmed to be part of a sequence.
+
+ The flexible sequencing structure consists of two hardware enable inputs
+ (EN0, EN1), and 3 master sequencing timers called FPS0, FPS1 and FPS2.
+ Each master sequencing timer is programmable through its configuration
+ register to have a hardware enable source (EN1 or EN2) or a software enable
+ source (SW). When enabled/disabled, the master sequencing timer generates
+ eight sequencing events on different time periods called slots. The time
+ period between each event is programmable within the configuration register.
+ Each regulator, GPIO1, GPIO2, GPIO3, and 32KHz clock has a flexible power
+ sequence slave register which allows its enable source to be specified as
+ a flexible power sequencer timer or a software bit. When a FPS source of
+ regulators, GPIOs and clocks specifies the enable source to be a flexible
+ power sequencer, the power up and power down delays can be specified in
+ the regulators, GPIOs and clocks flexible power sequencer configuration
+ registers.
+
+ When FPS event cleared (set to LOW), regulators, GPIOs and 32KHz clock
+ are set into following state at the sequencing event that corresponds
+ to its flexible sequencer configuration register.
+
+ Sleep state: In this state, regulators, GPIOs and 32KHz clock get disabled
+ at the sequencing event.
+ Global Low Power Mode (GLPM): In this state, regulators are set in low
+ power mode at the sequencing event.
+
+ The configuration parameters of FPS is provided through sub-node "fps"
+ and their child for FPS specific. The child node name for FPS are "fps0",
+ "fps1", and "fps2" for FPS0, FPS1 and FPS2 respectively.
+
+ The FPS configurations like FPS source, power up and power down slots for
+ regulators, GPIOs and 32kHz clocks are provided in their respective
+ configuration nodes which is explained in respective sub-system DT
+ binding document.
+
+ There is need for different FPS configuration parameters based on system
+ state like when system state changed from active to suspend or active to
+ power off (shutdown).

+Multi-Function Devices (MFD)
+
+These devices comprise a nexus for heterogeneous hardware blocks containing
+more than one non-unique yet varying hardware functionality.
+
+A typical MFD can be:
+
+- A mixed signal ASIC on an external bus, sometimes a PMIC (Power Management
+ Integrated Circuit) that is manufactured in a lower technology node (rough
+ silicon) that handles analog drivers for things like audio amplifiers, LED
+ drivers, level shifters, PHY (physical interfaces to things like USB or
+ ethernet), regulators etc.
+
+- A range of memory registers containing "miscellaneous system registers" also
+ known as a system controller "syscon" or any other memory range containing a
+ mix of unrelated hardware devices.
+
+Optional properties:
+
+- compatible : "simple-mfd" - this signifies that the operating system
+ should consider all subnodes of the MFD device as separate and independent
+ devices, so not needing any resources to be provided by the parent device.
+ Similarly to how "simple-bus" indicates when to see subnodes as children for
+ a simple memory-mapped bus.
+ For more complex devices, when the nexus driver has to probe registers to
+ figure out what child devices exist etc, this should not be used. In the
+ latter case the child devices will be determined by the operating system.
+
+- ranges: Describes the address mapping relationship to the parent. Should set
+ the child's base address to 0, the physical address within parent's address
+ space, and the length of the address map.
+
+- #address-cells: Specifies the number of cells used to represent physical base
+ addresses. Must be present if ranges is used.
+
+- #size-cells: Specifies the number of cells used to represent the size of an
+ address. Must be present if ranges is used.
+
+Example:
+
+foo@1000 {
+ compatible = "syscon", "simple-mfd";
+ reg = <0x01000 0x1000>;
+
+ led@8.0 {
+ compatible = "register-bit-led";
+ offset = <0x08>;
+ mask = <0x01>;
+ label = "myled";
+ default-state = "on";
+ };

+Motorola CPCAP PMIC device tree binding
+
+Required properties:
+- compatible : One or both of "motorola,cpcap" or "ste,6556002"
+- reg : SPI chip select
+- interrupts : The interrupt line the device is connected to
+- interrupt-controller : Marks the device node as an interrupt controller
+- #interrupt-cells : The number of cells to describe an IRQ, should be 2
+- #address-cells : Child device offset number of cells, should be 1
+- #size-cells : Child device size number of cells, should be 0
+- spi-max-frequency : Typically set to 3000000
+- spi-cs-high : SPI chip select direction
+
+Optional subnodes:
+
+The sub-functions of CPCAP get their own node with their own compatible values,
+which are described in the following files:
+
+- Documentation/devicetree/bindings/power/supply/cpcap-battery.yaml
+- Documentation/devicetree/bindings/power/supply/cpcap-charger.yaml
+- Documentation/devicetree/bindings/regulator/cpcap-regulator.txt
+- Documentation/devicetree/bindings/phy/motorola,cpcap-usb-phy.yaml
+- Documentation/devicetree/bindings/input/cpcap-pwrbutton.txt
+- Documentation/devicetree/bindings/rtc/cpcap-rtc.txt
+- Documentation/devicetree/bindings/leds/leds-cpcap.txt
+- Documentation/devicetree/bindings/iio/adc/motorola,cpcap-adc.yaml
+
+The only exception is the audio codec. Instead of a compatible value its
+node must be named "audio-codec".
+
+Required properties for the audio-codec subnode:
+
+- #sound-dai-cells = <1>;
+- interrupts : should contain jack detection interrupts, with headset
+ detect interrupt matching "hs" and microphone bias 2
+ detect interrupt matching "mb2" in interrupt-names.
+- interrupt-names : Contains "hs", "mb2"
+
+The audio-codec provides two DAIs. The first one is connected to the
+Stereo HiFi DAC and the second one is connected to the Voice DAC.
+
+Example:
+
+&mcspi1 {
+ cpcap: pmic@0 {
+ compatible = "motorola,cpcap", "ste,6556002";

+ NXP BBNSM serves as non-volatile logic and storage for the system.

+ The RTC can retain its state and continues counting even when the

+ significant 32 bits of the real-time counter match the value in the
+ Time Alarm register.
+ The ON/OFF logic inside the BBNSM allows for connecting directly to
+ a PMIC or other voltage regulator device. both smart PMIC mode and
+ Dumb PMIC mode supported.

+title: Qualcomm SPMI PMICs multi-function device
+
+description: |
+ Some Qualcomm PMICs used with the Snapdragon series SoCs are interfaced
+ to the chip via the SPMI (System Power Management Interface) bus.
+ Support for multiple independent functions are implemented by splitting the
+ 16-bit SPMI peripheral address space into 256 smaller fixed-size regions, 256 bytes
+ each. A function can consume one or more of these fixed-size register regions.
+
+ The Qualcomm SPMI series includes the PM8941, PM8841, PMA8084, PM8998 and other
+ PMICs. These PMICs use a "QPNP" scheme through SPMI interface.
+ QPNP is effectively a partitioning scheme for dividing the SPMI extended
+ register space up into logical pieces, and set of fixed register
+ locations/definitions within these regions, with some of these regions
+ specifically used for interrupt handling.

+description: |
+ Ricoh RN5T567/RN5T618/RC5T619 is a power management IC family which
+ integrates 3 to 5 step-down DCDC converters, 7 to 10 low-dropout regulators,
+ GPIOs, and a watchdog timer. It can be controlled through an I2C interface.
+ The RN5T618/RC5T619 provides additionally a Li-ion battery charger,
+ fuel gauge, and an ADC.
+ The RC5T619 additionally includes USB charger detection and an RTC.

+ The reset can be triggered either programmatically, via one of

+ asserting RESETB pin low.
+
+ The following modes are supported
+
+ - 0; restart PMU,
+ - 1; reset all power off reset registers and force state to
+ switch to ACTIVE mode,
+ - 2; same as mode 1 and also pull RESETB pin down for 5ms,
+
+ For example, some hardware may require a full restart (mode 0)
+ in order to function properly as regulators are shortly
+ interrupted in this mode.

+
+maintainers:
+ - Matti Vaittinen <mazziesaccount@gmail.com>
+
+description:
+ BD72720 and BD73900 are single-chip power management ICs for
+ battery-powered portable devices. They integrate 10 bucks and 11 LDOs,
+ and a 3000 mA switching charger. ICs also include a Coulomb counter,
+ a real-time clock (RTC), GPIOs and a 32.768 kHz clock gate.
+
+# In addition to the properties found from the charger node, PMICs
+# use properties from a static battery node. Please see the:
+# Documentation/devicetree/bindings/power/supply/battery.yaml
+#
+# Following properties are used
+# when present:
+#
+# charge-full-design-microamp-hours: Battry capacity in mAh
+# voltage-max-design-microvolt: Maximum voltage
+# voltage-min-design-microvolt: Minimum voltage system is still operating.
+# degrade-cycle-microamp-hours: Capacity lost due to aging at each full
+# charge cycle.
+# ocv-capacity-celsius: Array of OCV table temperatures. 1/table.
+# ocv-capacity-table-<N>: Table of OCV voltage/SOC pairs. Corresponds
+# N.th temperature in ocv-capacity-celsius
+#
+# volt-drop-thresh-microvolt: Threshold for starting the VDR correction
+# volt-drop-soc: Table of capacity values matching the
+# values in VDR tables.
+#
+# volt-drop-temperatures-millicelsius: Temperatures corresponding to the volage
+# drop values given in volt-drop-[0-9]-microvolt
+#
+# volt-drop-[0-9]-microvolt: VDR table for a temperature specified in
+# volt-drop-temperatures-millicelsius
+#
+# VDR tables are (usually) determined for a specific battery by ROHM.
+# The battery node would then be referred from the charger node:
+#
+# monitored-battery = <&battery>;

+title: ST-Ericsson Analog Baseband AB8500 and AB8505
+
+maintainers:
+ - Linus Walleij <linusw@kernel.org>
+
+description:
+ the AB8500 "Analog Baseband" is the mixed-signals integrated circuit
+ handling power management (regulators), analog-to-digital conversion
+ (ADC), battery charging, fuel gauging of the battery, battery-backed
+ RTC, PWM, USB PHY and some GPIO lines in the ST-Ericsson U8500 platforms
+ in connection with the DB8500 digital baseband. The DB8500 PRCMU
+ communicates directly and autonomously with the AB8500 and thus it
+ appears as a subnode of the DB8500 PRCMU. An altered version called
+ AB8505 also exist, the difference in AB8505 is that some of the USB and
+ USB charging handling has changed, and it has an embedded USB-to-serial
+ converter. Most subblocks takes their interrupts directly from the
+ AB8500 embedded interrupt controller.

+title: System Controller Devices
+
+description: |
+ System controller node represents a register region containing a set
+ of miscellaneous registers. The registers are not cohesive enough to
+ represent as any specific type of device. The typical use-case is
+ for some other node's driver, or platform-specific code, to acquire
+ a reference to the syscon node (e.g. by phandle, node path, or
+ search using a specific compatible value), interrogate the node (or
+ associated OS driver) to determine the location of the registers,
+ and access the registers directly.

+* Toshiba TC3589x multi-purpose expander
+
+The Toshiba TC3589x series are I2C-based MFD devices which may expose the
+following built-in devices: gpio, keypad, rotator (vibrator), PWM (for
+e.g. LEDs or vibrators) The included models are:
+
+- TC35890
+- TC35892
+- TC35893
+- TC35894
+- TC35895
+- TC35896
+
+Required properties:
+ - compatible : must be "toshiba,tc35890", "toshiba,tc35892", "toshiba,tc35893",
+ "toshiba,tc35894", "toshiba,tc35895" or "toshiba,tc35896"
+ - reg : I2C address of the device
+ - interrupts : the interrupt on the parent the controller is connected to
+ - interrupt-controller : marks the device node as an interrupt controller
+ - #interrupt-cells : should be <1>, the first cell is the IRQ offset on this
+ TC3589x interrupt controller.
+
+Optional nodes:
+
+- GPIO
+ This GPIO module inside the TC3589x has 24 (TC35890, TC35892) or 20
+ (other models) GPIO lines.
+ - compatible : must be "toshiba,tc3589x-gpio"
+ - interrupts : interrupt on the parent, which must be the tc3589x MFD device
+ - interrupt-controller : marks the device node as an interrupt controller
+ - #interrupt-cells : should be <2>, the first cell is the IRQ offset on this
+ TC3589x GPIO interrupt controller, the second cell is the interrupt flags
+ in accordance with <dt-bindings/interrupt-controller/irq.h>. The following
+ flags are valid:
+ - IRQ_TYPE_LEVEL_LOW
+ - IRQ_TYPE_LEVEL_HIGH
+ - IRQ_TYPE_EDGE_RISING
+ - IRQ_TYPE_EDGE_FALLING
+ - IRQ_TYPE_EDGE_BOTH
+ - gpio-controller : marks the device node as a GPIO controller
+ - #gpio-cells : should be <2>, the first cell is the GPIO offset on this
+ GPIO controller, the second cell is the flags.
+
+- Keypad
+ This keypad is the same on all variants, supporting up to 96 different
+ keys. The linux-specific properties are modeled on those already existing
+ in other input drivers.
+ - compatible : must be "toshiba,tc3589x-keypad"
+ - debounce-delay-ms : debounce interval in milliseconds
+ - keypad,num-rows : number of rows in the matrix, see
+ bindings/input/matrix-keymap.txt
+ - keypad,num-columns : number of columns in the matrix, see
+ bindings/input/matrix-keymap.txt
+ - linux,keymap: the definition can be found in
+ bindings/input/matrix-keymap.txt
+ - linux,no-autorepeat: do no enable autorepeat feature.
+ - wakeup-source: use any event on keypad as wakeup event.
+ (Legacy property supported: "linux,wakeup")
+
+Example:
+
+tc35893@44 {
+ compatible = "toshiba,tc35893";
+ reg = <0x44>;
+ interrupt-parent = <&gpio6>;
+ interrupts = <26 IRQ_TYPE_EDGE_RISING>;

+ #interrupt-cells = <2>;
+ gpio-controller;
+ #gpio-cells = <2>;
+ };

+ compatible = "toshiba,tc3589x-keypad";
+ interrupts = <6>;
+ debounce-delay-ms = <4>;
+ keypad,num-columns = <8>;

+Cirrus Logic/Wolfson Microelectronics wm831x PMICs
+
+System PMICs with a wide range of additional features.
+
+Required properties:
+
+ - compatible : One of the following chip-specific strings:
+ "wlf,wm8310"
+ "wlf,wm8311"
+ "wlf,wm8312"
+ "wlf,wm8320"
+ "wlf,wm8321"
+ "wlf,wm8325"
+ "wlf,wm8326"
+
+ - reg : I2C slave address when connected using I2C, chip select number
+ when using SPI.
+
+ - gpio-controller : Indicates this device is a GPIO controller.
+ - #gpio-cells : Must be 2. The first cell is the pin number and the
+ second cell is used to specify optional parameters (currently unused).
+
+ - interrupts : The interrupt line the IRQ signal for the device is
+ connected to.
+
+ - interrupt-controller : wm831x devices contain interrupt controllers and
+ may provide interrupt services to other devices.
+ - #interrupt-cells: Must be 2. The first cell is the IRQ number, and the
+ second cell is the flags, encoded as the trigger masks from
+ ../interrupt-controller/interrupts.txt
+
+Optional sub-nodes:
+ - phys : Contains a phandle to the USB PHY.
+ - regulators : Contains sub-nodes for each of the regulators supplied by
+ the device. The regulators are bound using their names listed below:
+
+ dcdc1 : DCDC1
+ dcdc2 : DCDC2
+ dcdc3 : DCDC3
+ dcdc4 : DCDC3
+ isink1 : ISINK1
+ isink2 : ISINK2
+ ldo1 : LDO1
+ ldo2 : LDO2
+ ldo3 : LDO3
+ ldo4 : LDO4
+ ldo5 : LDO5
+ ldo7 : LDO7
+ ldo11 : LDO11
+
+ The bindings details of each regulator can be found in:
+ ../regulator/regulator.txt
