STM32MP257F-DK - Using ST7789v with KMS DRM
Hello, I have a TFT LCD display that uses a ST7789v controller. I would like to interface with it using the KMS DRM subsystem in Linux. I have been having issues getting this to work though.
So far I have confirmed that the default driver to ST7789v controllers is running, but it only seems to create a drm_panel. I am having trouble creating/linking it to a connector/CRTC/encoder. I have any DBI related options enabled in menuconfig, but I don’t see any way to interface with DBI displays when running modetest.
Does anyone have any advice as to what I need to do to get DRM working with this display? Will I need to write my own drivers? I can provide any existing code/devicetree configurations if need be.
