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
+	  This is the default value for maximal ACL entries
+	  that are automatically appended into policy at "learning mode".
+	  Some programs access thousands of objects, so running

+	help
+	  Say Y here if you want to activate access control as soon as built-in
+	  policy was loaded. This option will be useful for systems where
+	  operations which can lead to the hijacking of the boot sequence are
+	  needed before loading the policy. For example, you can activate
+	  immediately after loading the fixed part of policy which will allow
+	  only operations needed for mounting a partition which contains the
+	  variant part of policy and verifying (e.g. running GPG check) and
+	  loading the variant part of policy. Since you can start using
+	  enforcing mode from the beginning, you can reduce the possibility of
+	  hijacking the boot sequence.
