cover drm/panel: Add Anbernic RG353V-V2 Panel

From: Chris Morgan <[email protected]>

Add the NewVision NV3051D panel as found on the second revision of the RG353V. The underlying LCD panel itself is unknown (ST7703 is the controller IC).

PATCH 1/2 dt-bindings: panel: Add compatible for Anbernic RG353V-V2 panel

From: Chris Morgan <[email protected]>

The Anbernic RG353V-V2 panel is a 5 inch 640x480 MIPI-DSI LCD panel. It's based on the ST7703 LCD controller just like rocktech,jh057n00900. It's used in a 2nd revision of the Anbernic RG353V handheld gaming device. Like the first revision of the RG353V the control chip is known but the panel itself is unknown, so name it for the device.

Re: [PATCH 2/2] drm/panel: st7703: Add support for Anbernic RG353V-V2 panel

Quoted 48 lines · Guido Günther

Hi,

Quoted 46 lines · Chris Morgan

From: Chris Morgan <[email protected]>

The Anbernic RG353V-V2 is a 5 inch panel used in a new revision of the Anbernic RG353V handheld gaming device. Add support for it.

Unfortunately it appears this controller is not able to support 120hz or 100hz mode like the first revision panel.

Thanks for catching this! Would make sense to split that into a separate commit. With that fixed

I can, if you would prefer. I just thought it was trivial so I wrapped it up in a single commit. I had a newer revision of the ST7703 datasheet on hand that had that command documented, but unfortunately not BF or a new command I added EF. If a new commit is preferred I'll resubmit early next week.

Thank you.
