[PATCH RFC v6 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.

This series is marked as RFC because it depends on a few other in review
series, GPU GX GDSC handling [1], QFPROM efuse for Milos [2], and devicetree
support for Glymur [3] (for a8xx RSCC offset fix and X2-185 bindings change).

Also depends on the GXCLKCTL block for Milos [4], but this is no longer in
review and has been applied.

Changes in v6:
- Re-jigged the register ranges for GPU/GMU to match Glymur
- Depend on RSCC offset fix
- Fix bindings to add constraints for reg list
- Link to v5: https://lore.kernel.org/r/20260502-adreno-810-v5-0-bc9fd2bb788d@xxxxx

Changes in v5:
- Sync with latest kgsl
- Link to v4: https://lore.kernel.org/r/20260416-adreno-810-v4-0-61676e073f8a@xxxxx

Changes in v4:
- Add 1150MHz speedbin
- Rebase on next-20260415
- Add dep on efuse patchset
- Link to v3: https://lore.kernel.org/r/20260407-adreno-810-v3-0-30cb7f196ed4@xxxxx

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
