Jernej Skrabec	1343bd6c23	drm/sun4i: Expand DE2 scaler lib with YUV support ... Basic principle of operation when using YUV framebuffer is that chroma planes have to be upscaled to same size as luma. Because of that, expand DE2 scaler library to support that. BSP driver uses another set of FIR filter coefficients for YUV planes.

Jernej Skrabec	b862a648de	drm/sun4i: Add support for HW scaling to DE2 ... Scaling is currently supported only for RGB framebuffers Coefficients and algorithm which coefficients to select are taken from BSP driver.
