[GIT PULL 1/2] Apple SoC driver changes for v6.17

[GIT PULL 1/2] Apple SoC driver changes for v6.17

[Sven Peter]

Hi Arnd,

Sorry for the very late pull requests this time, last weeks at work have been very
busy and I wasn't able to find time earlier.

This time we have two PRs for 6.17, the details are also in the signed tags:

- Driver updates which include making a rtkit memory management callback
  optional and dropping default ARCH_APPLE from our drivers in Kconfig.
  I wanted to instead select these in defconfig but that change isn't ready
  for this cycle.

- Device tree updates which include the bindings and nodes for our GPU driver.
  The driver itself isn't ready yet mainly due to rust dependencies but we're
  confident about the bindings and want to commit to keeping them stable.
  Otherwise there are a two smaller changes: removing another W=1 warning
  (which required a change to the binding itelf that'll also land in 6.17
  through the NVMEM tree) and adding a missing touchbar framebuffer node to
  the Apple T2 SoC device tree.


Best,


Sven

  soc: apple: rtkit: Make shmem_destroy optional (2025-07-19 14:52:36 +0200)

----------------------------------------------------------------
Apple SoC driver changes for v6.17

- Dropped default ARCH_APPLE from Kconfig
- Made shmem_destroy for coprocessor-managed buffers in the rtkit
  library optional since it's not required for e.g. SMC

  arm64: dts: apple: Add Apple SoC GPU (2025-07-21 15:22:10 +0000)

----------------------------------------------------------------
Apple SoC device tree changes for v6.17

- Added the bindings and nodes for Apple SoC GPU. The driver itself
  isn't ready for upstreaming yet due to rust dependencies but we're
  confident that the bindings are stable at this point.
- Added a missing node for the touchbar framebuffer to Apple T2 device
  trees, which is the BMC for some x86 Macs
- Fixed a W=1 warning by adding bit offsets to NVMEM node names. This
  required a change to the generic NVMEM cell binding which will be part
  of 6.17 through the NVMEM tree.
