It has been split off from [0] to facilitate easier merging. I have still kept it as v3 to maintain continuity with the previous patches. This series also includes conversion to YAML binding. Tested on TI's J721E with OV5640 sensor. [0] https://patchwork.linuxtv.org/project/linux-media/list/?series=5526&state=%2A&archive=both Changes in v3: - Use a table to select the band. - Use a table to poll the data lane ready bits. - Multiply the DPHY HS clock rate by 2 to get the bit rate since the clock is DDR. - Add Rob's R-by. Changes in v2: - Drop reg description. - Add a description for each DPHY clock. - Rename dphy@... to phy@... in example. - Add Laurent's R-by. - Re-order subject prefixes. - Re-order subject prefixes. - Add power-domain to the example. - Add Laurent's R-by. - Re-order subject prefixes.
