media: ov5640: Add three more test patterns
The OV5640 driver currently supports a static color bar pattern with a small vertical gamma gradient. The hardware also supports a color square pattern, as well as having a rolling bar for dynamic sequences. Add three more test patterns: - color bars with a rolling bar (but without the gamma gradient) - static color squares - color squares with a rolling bar Signed-off-by: Chen-Yu Tsai <wens@csie.org> Signed-off-by: Sakari Ailus <sakari.ailus@linux.intel.com> Signed-off-by: Mauro Carvalho Chehab <mchehab+samsung@kernel.org>
