Chris, could you please check that the new rg353v-panel-v2 works with the changes I proposed. Guido, could you please check that the jh057n00900 panel works with the changes I proposed. Without these patches the XBD599 panel does not work reliably, so in the long run it's desirable to include them in mainline. Currently, the only user of the XBD599 panel that I'm aware of is the pinephone. Therefore, all distributions supporting the pinephone rely on out-of-tree patches to support the XDB599 panel. I'd appreciate if we could rectify this situation.

Hi Chris,
could you check if these two modifications by Frank of the init sequence
https://lore.kernel.org/dri-devel/20230211171748.36692-2-fr...@oltmanns.dev/
https://lore.kernel.org/dri-devel/20230213123238.76889-2-fr...@oltmanns.dev/
work for your panel too?
Cheers,

[PATCH V3 1/3] dt-bindings: panel: Add Anbernic RG353V-V2 panel compatible
From: Chris Morgan The Anbernic RG353V-V2 panel is a 3.5 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.
