* drm/sun4i: Expand DE2 scaler lib with YUV supportJernej Skrabec2017-12-051-1/+3
| | | | | | | | | | | | | 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.

* drm/sun4i: Add support for HW scaling to DE2Jernej Skrabec2017-12-051-0/+56
Scaling is currently supported only for RGB framebuffers Coefficients and algorithm which coefficients to select are taken from BSP driver.
