> This patch adds a new format_set() callback to the bridge ops permitting

> 
> This allows supporting the very specific HDMI2.0 YUV420 output mode
> when the bridge cannot convert from RGB or YUV444 to YUV420.
> 
> In this case, the encode must downsample before the bridge and must
> specify the bridge the new input bus format differs.
> 
> This will also help supporting the YUV420 mode where the bridge cannot
> downsample, and also support 10bit, 12bit and 16bit output modes
> when the bridge cannot convert between different bit depths.
