Subject: [PATCH 0/7] drm/panel: nv3052c: Fix Anbernic RG35XX panel support (and add RG40XX panel)

Fix support for panels used in the Anbernic RG35XX series.

We previously decided to use the integrated vendor and device name for the panel, but the recent revision of the RG35XX series has a different panel that is not compatible with the old panel.
Unfortunately, these two RG35XX models have the same name and cannot be distinguished without opening them, so the name `anbernic,rg35xx-plus-panel` is no longer suitable as a unique identifier.

This patch series fixes the situation by:
* Renaming rg35xx-plus-panel back to WL-355608-A8, but with a vendor-prefixed `anbernic,wl-355608-a8` for the older RG35XX series
* Adding new panel, YLM-LBV0345001H-V2 (`anbernic,ylm-lbv0345001h-v2`), for the newer RG35XX series
(Detecting the connected panel is another problem.)

Additionally, this patch series adds another panel, YLM-LBV0400001X-V1 (`anbernic,ylm-lbv0400001x-v1`), which is similar to YLM-LBV0345001H-V2, for the RG40XX series.

This patch series should be applied after:
