[PATCH RFC v3 0/7] Add support for Adreno 810 GPU

[Alexander Koskovich]

Adreno 810 is present in the Milos SoC and is the first GPU to be released in
the A8x family.

Note that the OPP table is limited to 1050MHz to start with as the only Milos
device I have is limited to that speed in GPU_CC_FREQ_LIMIT_VAL.

This series is marked as RFC because it depends on a couple other in review
series, GPU GX GDSC handling [1] and the GXCLKCTL block for Milos [2].

Also depends on A8x batch 2 but it looks like that made it into linux-next.

Changes in v3:
- Drop DEMET from GMU clocks (not required on A810)
- Document qcom,adreno-44010000 compatible (regex is gone in 7.0+)
- Drop zeroed out CP_PROTECT_REG[46, 62] range, not required
- Add a810_protect to __build_asserts
- Add UCHE_CCHE_TRAP_BASE_[LO|HI] and UCHE_CCHE_WRITE_THRU_BASE_[LO|HI] to a810_pwrup_reglist_regs
- Move TPL1 registers to a810_pwrup_reglist_regs
- Include all protect registers in a810_ifpc_reglist_regs
- Revert pipe reg comment, just copied it from downstream but original also works
- Link to v2: https://lore.kernel.org/r/20260402-adreno-810-v2-0-ce337ca87a9e@xxxxx

Changes in v2:
- Mark as RFC due to dependency on in-review changes
- Explain in DTS commit why qcom,kaanapali-gxclkctl.h and not qcom,milos-gxclkctl.h
- cx_mmio -> cx_misc_mmio
- Sync a810_nonctxt_regs with GRAPHICS.LA.14.0.r5-03100-lanai.0
- Link to v1: https://lore.kernel.org/r/20260331-adreno-810-v1-0-725801dbb12b@xxxxx
