[PATCH v2 1/2] v4l: vsp1: Add support for colorkey alpha blending

2017-05-07 Thread Alexandru Gheorghe
The vsp2 hw supports changing of the alpha of pixels that match a color key, this patch adds support for this feature in order to be used by the rcar-du driver. The colorkey is interpreted different depending of the pixel format: * RGB - all color components have to match. * YCbCr
