- Subject: [PATCH] drm: vc4: enable XBGR8888 and ABGR8888 pixel formats
- DRM_FORMAT_XBGR8888 and DRM_FORMAT_ABGR8888 are 2 of the native formats
- used in Android, so enable them for VC4. There seems to be no logic behind
- HVS_PIXEL_ORDER_xxxx naming, but HVS_PIXEL_ORDER_ARGB seems to work
- correctly.
- Signed-off-by: Rob Herring <robh@kernel.org>
- Reviewed-by: Eric Anholt <eric@anholt.net>
- (cherry picked from commit 93977767f092fbf0787e5d2a0bf2e0a3fc6f6ced)
