   4 Subject: [PATCH] drm: vc4: enable XBGR8888 and ABGR8888 pixel formats
   5
   6 DRM_FORMAT_XBGR8888 and DRM_FORMAT_ABGR8888 are 2 of the native formats
   7 used in Android, so enable them for VC4. There seems to be no logic behind
   8 HVS_PIXEL_ORDER_xxxx naming, but HVS_PIXEL_ORDER_ARGB seems to work
   9 correctly.
