Patch Review

**Status: Looks good overall, a few observations**

This is the main patch adding the A810 catalog entry with register tables. Key observations:

**Catalog entry structure:**
```c
.chip_ids = ADRENO_CHIP_IDS(0x44010000),
.family = ADRENO_8XX_GEN1,
.fw = {
    [ADRENO_FW_SQE] = "gen80300_sqe.fw",
    [ADRENO_FW_GMU] = "gen80300_gmu.bin",
},
.gmem = SZ_512K + SZ_64K,
```

- Family is `ADRENO_8XX_GEN1` (a830 family) — this makes sense as A810 is the "first GPU to be released in the A8x family" per the cover letter, so it's in the earlier gen.
- The existing A8xx GPUs (x285, a840) are `ADRENO_8XX_GEN2` with massive GMEM (18-21MB). A810 has only 576KB — much smaller, consistent with being a lower-tier part.
- Firmware is `gen80300` — distinct from x285's `gen80100` and a840's `gen80200`.
- No `[ADRENO_FW_AQE]` entry unlike A840, which is fine for a simpler GPU.

**Quirks:**
```c
.quirks = ADRENO_QUIRK_HAS_CACHED_COHERENT |
          ADRENO_QUIRK_HAS_HW_APRIV |
          ADRENO_QUIRK_PREEMPTION |
          ADRENO_QUIRK_IFPC,
```
This matches A840's quirk set. No `ADRENO_QUIRK_SOFTFUSE` (unlike x285), which means speedbin reads will use the nvmem fuse path rather than the cx_misc softfuse path.

**Protect table:**
`DECLARE_ADRENO_PROTECT(a810_protect, 64)` — 47 entries out of 64 max global slots. The `__build_asserts` check is properly added.

**Register tables:**
The `a810_nonctxt_regs`, `a810_pwrup_reglist_regs`, `a810_ifpc_reglist_regs`, and `a810_dyn_pwrup_reglist_regs` are all A810-specific, which is expected as register values differ between GPU generations.

**`adreno_is_a810()` helper:**
```c
+static inline int adreno_is_a810(struct adreno_gpu *gpu)
+{
+	return gpu->info->chip_ids[0] == 0x44010000;
+}
```
This is added but I don't see it used in this series. It follows the existing pattern (e.g., `adreno_is_x285()`). Worth confirming it's needed — it may be used by future patches or by the dependent series.

**`a810_dyn_pwrup_reglist_regs` includes `REG_A8XX_CP_PROTECT_PIPE(15)`:**
```c
{ REG_A8XX_CP_PROTECT_PIPE(15), 0, BIT(PIPE_BR) | BIT(PIPE_BV) },
```
This is consistent with the hardcoded slot 15 from patch 5.

**Minor**: The `a810_nonctxt_regs` has a comment `/* Avoid partial waves at VFD */` on the BV-specific `PC_CHICKEN_BITS_1` entry, while the BR entry has no comment. This is fine as it explains why the BV value differs (0x23 vs 0x03).

**Observation on `max_slices = 1`**: A810 is a single-slice GPU, compared to x285 (4 slices) and a840 (3 slices). This is consistent with it being a lower-tier part.

No blocking issues found.
