Decoder hardware produces MT21 (compressed). Image processor can
convert it to a format that can be input of display driver. Tiffany.
When do you plan to upstream image processor (mtk-mdp)?

I remember display driver can only accept uncompressed MT21. Right?
Basically V4L2_PIX_FMT_MT21 is compressed and is like an opaque
format. It's not usable until it's decompressed and converted by image
processor.
