Display engine drivers often need to distinguish between different types of
YUV sub-sampling. This introduces helpers to check for common sub-sampling
ratios in their commonly-used denomination from the DRM format info.

Hi,
I'm looking at the sun4i DRM driver these days (especially for
mainlining the VPU tiled format support through the frontend).
The way things are done currently, all the possibly-supported plane
formats are listed in sun4i_backend_layer_formats and exposed as-is to
userspace for every plane.
This adds the pin muxing definition for configuring the PD pins in LCD0
mode for a RGB888 format to the sun7i device-tree.

This introduces support for HEVC/H.265 to the Cedrus VPU driver, with
both uni-directional and bi-directional prediction modes supported.
Field-coded (interlaced) pictures, custom quantization matrices and
10-bit output are not supported at this point.
