Hello,

This small patch series improves YUV support in the i.MX8MP LCDIF
driver. After patches 1/4 and 2/4 that fix tiny cosmetic issues, patch
3/4 fixes YUV quantization range for the RGB to YUV conversion. Patch
4/4 addresses the other direction and adds support for YUV planes.

Please see individual patches for details.

The series has been tested on a Polyhex Debix board with the currently
out-of-tree HDMI encoder support patches developed by Lucas Stach.
