The ADV7393 and ADV7391 are register compatible and covered in the same datasheet.

 

However the ADV7391 lacks the 16-bit wide RGB interface mode out /dev/fb driver uses.

 

So if you like to use it as framebuffer device please use the ADV7392 or ADV7393

Framebuffers are typically in the RGB color space.

The ADV7393 driver supports 16-bit RGB565. But the fb driver has an

experimental option to support YCbCr 4:2:2 as well.
