From 4352b8aee98005853aa63f57d6377282de17a33f Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Sun, 23 Aug 2026 13:28:57 -0700 Subject: Merge tag 'i3c/for-7.3' of git://git.kernel.org/pub/scm/linux/kernel/git/i3c/linux Pull I3C updates from Alexandre Belloni: "A new driver this cycle, for the AMD AXI I3C controller. There are also new features such as IBI wakeup support, SETAASA device discovery and ACPI support for the the DAA methods, meaning we can now communicate with the SPD devices on DDR5 modules. New driver: - AMD AXI I3C master controller Subsystem: - I3C Common Command Code (CCC) handling improvements, especially around GET CCCs - SETAASA device discovery support - ACPI support for all existing DAA methods like SETDASA, SETNEWDA as well as I2C devices on I3C bus - IBI-based wakeup support Drivers: - dw: SETAASA support - mipi-i3c-hci: advertise IBI wakeup capability, AMD_PT I3C controller support, PIO queue management support for HCI v1.2 - renesas: improve suspend to RAM support, add runtime PM support" * tag 'i3c/for-7.3' of git://git.kernel.org/pub/scm/linux/kernel/git/i3c/linux: (70 commits) i3c: dw: reduce do_daa time if there's no client i3c: mipi-i3c-hci: Add support for AMD_PT I3C controller i3c: mipi-i3c-hci: Add PIO queue management support for HCI v1.2 i3c: mipi-i3c-hci: Fix missing STAT_IBI_STATUS_THLD in PIO mode i3c: dw: rename "pclk" to "apb" to match dt-binding i3c: dw: make struct dw_i3c_cmd smaller i3c: dw: use COMMAND_PORT_TRANSFER_ARG instead of hardcoding i3c: renesas: Don't register devices when ENTDAA times out i3c: master: dw-i3c-master: fix OD timing for first broadcast i3c: mipi-i3c-hci: Advertise IBI wakeup capability i3c: mipi-i3c-hci: Factor out i3c_hci_sysdev() i3c: mipi-i3c-hci-pci: Propagate I3C wakeup requirements to PCI i3c: master: Reject IBI requests from non-IBI-capable devices i3c: master: Add helper to query bus wakeup requirements i3c: master: Report wakeup events for IBIs i3c: master: Support IBI-based wakeup capability i3c: master: Fix potential UAF in i3c_device_match() i3c: master: Fix potential UAF in i3c_device_uevent() i3c: Make dev->desc locking assumptions explicit i3c: master: Fix use-after-free of master->this ... --- drivers/clocksource/timer-of.h | 72 ++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 72 insertions(+) create mode 100644 drivers/clocksource/timer-of.h (limited to 'drivers/clocksource/timer-of.h') diff --git a/drivers/clocksource/timer-of.h b/drivers/clocksource/timer-of.h new file mode 100644 index 000000000..74a632b85 --- /dev/null +++ b/drivers/clocksource/timer-of.h @@ -0,0 +1,72 @@ +/* SPDX-License-Identifier: GPL-2.0 */ +#ifndef __TIMER_OF_H__ +#define __TIMER_OF_H__ + +#include + +#define TIMER_OF_BASE 0x1 +#define TIMER_OF_CLOCK 0x2 +#define TIMER_OF_IRQ 0x4 + +struct of_timer_irq { + int irq; + int index; + const char *name; + unsigned long flags; + irq_handler_t handler; +}; + +struct of_timer_base { + void __iomem *base; + const char *name; + int index; +}; + +struct of_timer_clk { + struct clk *clk; + const char *name; + int index; + unsigned long rate; + unsigned long period; +}; + +struct timer_of { + unsigned int flags; + struct device_node *np; + struct clock_event_device clkevt; + struct of_timer_base of_base; + struct of_timer_irq of_irq; + struct of_timer_clk of_clk; + void *private_data; +}; + +static inline struct timer_of *to_timer_of(struct clock_event_device *clkevt) +{ + return container_of(clkevt, struct timer_of, clkevt); +} + +static inline void __iomem *timer_of_base(struct timer_of *to) +{ + return to->of_base.base; +} + +static inline int timer_of_irq(struct timer_of *to) +{ + return to->of_irq.irq; +} + +static inline unsigned long timer_of_rate(struct timer_of *to) +{ + return to->of_clk.rate; +} + +static inline unsigned long timer_of_period(struct timer_of *to) +{ + return to->of_clk.period; +} + +int timer_of_init(struct device_node *np, struct timer_of *to); + +void timer_of_cleanup(struct timer_of *to); + +#endif -- cgit v1.3.1
