Merge tag 'i3c/for-7.3' of git://git.kernel.org/pub/scm/linux/kernel/git/i3c/linuxgrafted

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"

+	help
+	  Universal Serial Bus (USB) is a specification for a serial bus
+	  subsystem which offers higher speeds and more features than the
+	  traditional PC serial port.  The bus supplies power to peripherals
+	  and allows for hot swapping.  Up to 127 USB peripherals can be
+	  connected to a single USB host in a tree structure.
+	  
+	  The USB host is the root of the tree, the peripherals are the
+	  leaves and the inner nodes are special USB devices called hubs.
+	  Most PCs now have USB host ports, used to connect peripherals
+	  such as scanners, keyboards, mice, modems, cameras, disks,
+	  flash memory, network links, and printers to the PC.
+
+	  Say Y here if your computer has a host-side USB port and you want
+	  to use USB devices.  You then need to say Y to at least one of the
+	  Host Controller Driver (HCD) options below.  Choose a USB 1.1
+	  controller, such as "UHCI HCD support" or "OHCI HCD support",
+	  and "EHCI HCD (USB 2.0) support" except for older systems that
+	  do not have USB 2.0 support.  It doesn't normally hurt to select
+	  them all if you are not certain.
+
+	  If your system has a device-side USB port, used in the peripheral
+	  side of the USB protocol, see the "USB Gadget" framework instead.
+
+	  After choosing your HCD, then select drivers for the USB peripherals
+	  you'll be using.  You may want to check out the information provided
+	  in <file:Documentation/usb/> and especially the links given in
+	  <file:Documentation/usb/usb-help.rst>.
+
+	  To compile this driver as a module, choose M here: the
+	  module will be called usbcore.
+
+config USB_PCI
+	bool "PCI based USB host interface"
+	depends on PCI
+	default y
+	help
+	  Many embedded system SOCs (e.g. freescale T2080) have both
+	  PCI and USB modules with the USB module directly controlled by
+	  registers and having no relationship to the PCI module.
+
+	  If you have such a device you may say N here and PCI related code
+	  will not be built in the USB driver.
+
+config USB_PCI_AMD
+	bool "AMD PCI USB host support"
+	depends on USB_PCI && HAS_IOPORT
+	default X86 || MACH_LOONGSON64 || PPC_PASEMI
+	help
+	  Enable workarounds for USB implementation quirks in SB600/SB700/SB800
+	  and later south bridge implementations. These are common on x86 PCs
+	  with AMD CPUs but rarely used elsewhere, with the exception of a few
+	  powerpc and mips desktop machines.
