Applied thanks.

Couldn't help but notice that :
@@ -312,7 +312,7 @@ static void ipu_ch_param_set_size(union
chan_param_mem *params,
        case IPU_PIX_FMT_RGB565:
                params->ip.bpp  = 2;
                params->ip.pfs  = 4;

is not really good way. Someone else who is using this driver has no way
of knowing what these magic numbers mean and how to use them
Perhaps you can add meaning to these numbers and some note on why they
should be set to these values.
