| Subject: v4l: Add ARGB and XRGB pixel formats |
| |
| The existing RGB pixel formats are ill-defined in respect to their alpha |
| bits and their meaning is driver dependent. Create new standard ARGB and |
| XRGB variants with clearly defined meanings and make the existing |
| variants deprecated. |
| |
| The new pixel formats 4CC values have been selected to match the DRM |
| 4CCs for the same in-memory formats. |
