[PATCH v2] drm/panel-edp: Add AUO B133HAN06.6 and BOE NV133FHM-N4F V8.0

[Chen-Yu Tsai]

These two panels are found in MT8195 Dojo, a.k.a. the HP Chromebook
x360 13b-ca0xxx laptop.

Only the BOE entry was tested on an actual device. The AUO entry is
solely based on the provided datasheet.

I'd previously seen the AUO 0xcb8f panel as one missing and the EDID I
gathered matches your datasheet.

This is a single, straightforward patch adding two new eDP panel entries for panels found in the HP Chromebook x360 13b-ca0xxx (MT8195 Dojo). The patch is well-formed: raw EDIDs are included in the commit message (added in v2), product IDs correctly decoded from those EDIDs, sort order is maintained in both the AUO and BOE table sections, and both referenced delay structures exist.

The BOE panel was tested on actual hardware; the AUO entry is based solely on the datasheet. Both panels are 13.3" FHD (1920x1080) eDP panels based on the EDID detailed timing descriptors.

**Verdict: Patch looks good.**

Patch Review

**EDID verification:** Both product IDs are correctly extracted from the provided raw EDIDs. AUO bytes `8f cb` → 0xcb8f and BOE bytes `25 0a` → 0x0a25. Manufacturer IDs also decode correctly.

**Sort order:** Both entries are inserted in the correct ascending order by product ID:
- AUO: 0xc9a8 < **0xcb8f** < 0xcdba ✓
- BOE: 0x0a1b < **0x0a25** < 0x0a36 ✓

**Delay structures:**

```c
EDP_PANEL_ENTRY('A', 'U', 'O', 0xcb8f, &delay_200_500_e50, "B133HAN06.6"),
```
Uses `delay_200_500_e50` (hpd_absent=200, unprepare=500, enable=50) — a common default for AUO panels. Reasonable for a datasheet-only entry, consistent with neighboring AUO entries that use the same delay.

```c
EDP_PANEL_ENTRY('B', 'O', 'E', 0x0a25, &delay_200_500_e50_po2e200, "NV133FHM-N4F V8.0"),
```
Uses `delay_200_500_e50_po2e200`, which adds `powered_on_to_enable=200` on top of the base delays. Since this was hardware-tested, the choice of a delay with `powered_on_to_enable` is presumably validated. The nearby BOE entry at 0x0a1b uses the simpler `delay_200_500_e50`, so the difference is intentional and worth noting — the `powered_on_to_enable` delay likely reflects an observed requirement on this specific panel/board combination.

**Minor observation (not blocking):** The AUO panel was not tested on hardware. The commit message is transparent about this ("solely based on the provided datasheet"). If the delay turns out to be wrong, it can be adjusted later — standard practice for this table.

**No issues found.** Reviewed-by would be appropriate.
