[PATCH v2 0/3] drm/panel: ilitek-ili9488: add the PocketGo S30 panel

[Romain TISSERAND <romain.tisserand@gmail.com>]

The Miyoo PocketGo S30 is an Allwinner A33 handheld with a 320x480
1-lane MIPI-DSI panel built around an Ilitek ILI9488. The panel uses the
existing ILI9488 DSI driver with its own init sequence (from the stock
kernel), timings and DSI mode; the sequence is close to the
E35GH-I-MW800CB one.

Patch 1 makes the binding's port optional: the Allwinner sun6i DSI host
links its panel as a child node and has no output port, and the driver
does not use one. Patch 2 adds the compatible, patch 3 the panel. The
board devicetree will be sent to the sunxi tree separately.

Testing: each patch built with W=1 for arm (multi_v7_defconfig,
DRM_PANEL_ILITEK_ILI9488=y and =m) and arm64 (defconfig, =m), no
warnings; dt_binding_check clean for ilitek,ili9488.yaml. Tested on a
PocketGo S30 on 7.3.1 with v1 (A33 sun6i DSI, one lane): the panel
probes and attaches to the DSI host, and the picture shows the right
colors, size and position. v2 only renames the compatible and edits a
commit message.

Changes in v2:
- Drop the "pocketgo" vendor prefix patch: PocketGo is a product line,
  not a company (Krzysztof). The S30 is made by Bittboy/Miyoo, so use
  the existing "miyoo" prefix: "miyoo,pocketgo-s30-panel".
- 3/3: drop the claim that COLMOD sets the panel to 6 bits per color
  over DSI, only say the stock value is kept (Igor).
- Add Igor's Reviewed-by. I kept it on 2/3 and 3/3 although their
  compatible changed from "pocketgo,s30-panel" to
  "miyoo,pocketgo-s30-panel"; nothing else changed in them.
- Link to v1: https://lore.kernel.org/all/20261103110524.2812831-1-romain.tisserand@gmail.com/

Tool disclosure: this series was prepared with Claude Opus 5.5
(Anthropic) as a coding assistant, in an interactive session: it
extracted the stock init table and timings, wrote the code, the
bindings and the messages. I reviewed and understand it, and tested it
as described.
