18ddd99a01 dt-bindings: pps: gpio: Correct indentation and style in DTS example
DTS example in the bindings should be indented with 2- or 4-spaces and
aligned with opening '- |', so correct any differences like 3-spaces or
mixtures 2- and 4-spaces in one binding.

No functional changes here, but saves some comments during reviews of
new patches built on existing code.

a414016218 ima: limit the number of ToMToU integrity violations
Each time a file in policy, that is already opened for read, is opened
for write, a Time-of-Measure-Time-of-Use (ToMToU) integrity violation
audit message is emitted and a violation record is added to the IMA
measurement list.  This occurs even if a ToMToU violation has already
been recorded.

Limit the number of ToMToU integrity violations per file open for read.

Note: The IMA_MAY_EMIT_TOMTOU atomic flag must be set from the reader
side based on policy.  This may result in a per file open for read
ToMToU violation.

Since IMA_MUST_MEASURE is only used for violations, rename the atomic
IMA_MUST_MEASURE flag to IMA_MAY_EMIT_TOMTOU.

 "There is new support for additional on-chip devices on Apple,

  Amlogic devices.

  The Arm Morello reference platform gets a devicetree for booting in
  normal aarch64 mode. The hardware supports experimental CHERI support,
  which requires a modified kernel.

  The AMD (formerly Xilinx) Versal NET SoC gets added, this is a
  combined FPGA with Cortex-A78 CPUs in a SoC.

  Six new ST STM32MP2 SoC variants are added. Like the earlier
  STM32MP25, the MP211, MP213, MP215, MP231, MP233 and MP235 models are
  based on one or two Cortex-A35 cores but each feature a different set
  of I/O devices.

  Mediatek MT8370 is a minor variation of MT8390 with fewer CPU and GPU
  cores

  Apple T2 is the baseboard management controller on earlier Intel CPU
  based Macs, with 16 models now gaining initial support.

  All the above come with dts files for the reference boards. In
  addition, these boards are added for the SoCs that are already
  supported:

   - The Milk-V Jupiter board based on SpacemiT K1/M1

   - NetCube Systems Kumquat board based on the 32-bit Allwinner V3s SoC

   - Three boards based on 32-bit stm32mp1

   - 11 distinct board variants from Toradex and one from Variscite, all
     based on i.MX6

   - Google Pixel Pro 6 phone based on gs101 (Tensor)

   - Three additional variants of the i.MX8MP based "Skov" board

   - Four boards based the Rockchip RK35xx series, plus the RK3588 'MNT

Lazy flushing of TPM auth sessions can interact badly with IMA + kexec,

the TPM is told about the shutdown, matching what is done when
suspending.

9afb9eaa9f tpm_crb: Add support for the ARM FF-A start method
The TCG ACPI spec v1.4 defines a start method for the TPMs implemented with
the ARM CRB over FF-A ABI.

Add support for the FF-A start method, and use interfaces provided by the
ffa_crb driver to interact with the FF-A based TPM.
