Could you precise which SKU you're referring to ? is it 19885 => https://www.waveshare.com/7inch-dsi-lcd.htm ?

Are you sure it requires different timings from the RPi one ? In the Waveshare
wiki it explicitly uses the rpi setup (vc4-kms-dsi-7inch) to drive it: https://www.waveshare.com/wiki/7inch_DSI_LCD
