[PATCH v2 0/3] Arm China Linlon-D6 display controller support

[Cunyuan Liu <cunyuan.liu@cixtech.com>]

Adds Komeda DRM support for Arm China Linlon-D6. The IP is register-compatible
with Mali-D71, so we reuse the D71 code path.

  [1/3] dt-bindings: vendor-prefixes: add Arm Technology (China) "armchina"
  [2/3] dt-bindings: add armchina,linlon-d6 compatible (fallback to arm,mali-d71)
  [3/3] drm/komeda: add Linlon-D6 product ID and of_device_id, use D71 funcs

Changes in v2:
- PATCH [2/3]: rework compatible schema using enum as suggested by Krzysztof.

v1: https://lore.kernel.org/dri-devel/20260311055506.12023-1-cunyuan.liu@cixtech.com/

Tested on Radxa Orion O6 with Linlon-D6, basic display bring-up works as expected.

Thanks,
Cunyuan
