Interfacing with standard DRM? #6

Open Jookia opened 1 year ago

Jookia commented 1 year ago

I attempted to use this to create a panel used for an Allwinner LCD controller but found it didn't make the calls to the drm subsystem to register the panel. The panel takes commands over SPI but data over an RGB signal.

Is this an intentional design choice or lacking feature?

This driver does only work with MIPI DBI controllers that receives the pixels over the SPI bus. Someone would have to write similar drivers for MIPI DPI(RGB)/DSI in order to support those pixel buses.

Oh okay, that makes sense. I didn't know pixels get sent over the bus. Thanks for the explanation.
