Subject: [PATCH 2/2] drm/komeda: Add format support for Y0L2, P010,
YUV420_8/10BIT
- Y0L2 and P010 are block (tiled) format, Update the kemeda logic to
compatible with such block format.
- Since DRM introduced a general block information to drm_format_info,
the format_caps->tiled_size no long needed, delete it.
- Build some fb utils functions for code sharing.
