Subject: [PATCH v2 0/5] Support for Adreno X1-85 GPU

This series adds support for the Adreno X1-85 GPU found in Qualcomm's
compute series chipset, Snapdragon X1 Elite (x1e80100). In this new
naming scheme for Adreno GPU, 'X' stands for compute series, '1' denotes
1st generation and '8' & '5' denotes the tier and the SKU which it
belongs.

X1-85 has major focus on doubling core clock frequency and bandwidth
throughput. It has a dedicated collapsible Graphics MX rail (gmxc) to
power the memories and double the number of data channels to improve
bandwidth to DDR.

Mesa has the necessary bits present already to support this GPU. We are
able to bring up Gnome desktop by hardcoding "0xffff43050a01" as
chipid. Also, verified glxgears and glmark2. We have plans to add the
new chipid support to Mesa in next few weeks, but these patches can go in
right away to get included in v6.11.

This series is rebased on top of msm-next branch. P3 cherry-picks cleanly on
qcom/for-next.

P1, P2 & P3 for Rob Clark
P4 for Will Deacon
P5 for Bjorn to pick up.

Changes in v2:
- Minor update to compatible pattern, '[x]' -> 'x'
- Increased address space size (Rob)
- Introduced gmu_chipid in a6xx_info (Rob)
- Improved fallback logic for gmxc (Dmitry)
- Rebased on top of msm-next
- Picked a new patch for arm-mmu bindings update
- Reordered gpu & gmu reg enties to match schema

Akhil P Oommen (5):
  dt-bindings: display/msm/gmu: Add Adreno X185 GMU
  drm/msm/adreno: Add support for X185 GPU
