From: Hans Verkuil <hans.verkuil@xxxxxxxxx> This patch series adds support for most of the 4:2:0 formats that V4L2 has. In addition, it fixes various bugs, adds some new features and refactors the test pattern generation code. The first 8 patches fix bugs and add support for new red/blue checkerboard patterns. Patches 9-19 add 4:2:0 support to the test pattern generator code. Patches 20-25 refactors the test pattern generation function which become much, much too large. Patches 26-28 add vivid driver support for the 4:2:0 formats and the last patch finally enables support for the new formats. Besides the new 4:2:0 formats support was also added for PIX_FMT_GREY and some missing 4:2:2 formats.
