Actually there is a driver and config DRM_PANEL_SITRONIX_ST7789V, in
gpu/drm/panel/panel-sitronix-st7789v.c and also FB_TFT_ST7789V and
CONFIG_FB_TFT_ST7789V with the driver a in
staging/fbtft/fb_st7789v.c. Might be easier :)
Weird that the Kendryte SDK refers to the LCD as NT35310
(https://github.com/kendryte/kendryte-standalone-demo/tree/develop/lcd).

Nice, gonna take a look at it.
