This is a clean, minimal 3-patch series adding support for the Arm China Linlon-D6 display controller to the existing Komeda/Mali-D71 DRM driver. The approach is sound — the Linlon-D6 is described as register-compatible with Mali-D71, so reusing the D71 code path via a new compatible string with a fallback is the correct DT pattern. The changes are small and well-scoped.

One concern: the cover letter says the DT binding uses `"armchina,linlon-d6"` with a fallback to `"arm,mali-d71"`, but the **driver's `of_device_id` table only matches the specific `"armchina,linlon-d6"` compatible** — it does not rely on the fallback. This works, but it means the driver duplicates the match rather than relying on DT fallback semantics. This is consistent with how `arm,mali-d32` is handled (it also has both a binding fallback and an explicit driver match entry), so the pattern is fine.

No significant issues found. A few minor observations below.
