This series fixes the power-up sequence delays to support some 15-pin FFC compatible OV5640 modules. Without appropriate delays after both gpio and register-based powerdown and reset the sensor SCCB was not very stable, and probe would sometimes fail at check_chip_id. Changes in v4: - Swap order of patches [1/3] and [2/3] - Drop patch [3/3] as SW powerup does not have same timing constraints - Move soft powerdown from the register table to powerup_sequence() along with soft reset v3: https://lore.kernel.org/all/20221227173634.5752-1-j-luthra@xxxxxx/ Jai Luthra (2): media: ov5640: Fix soft reset sequence and timings media: ov5640: Handle delays when no reset_gpio set drivers/media/i2c/ov5640.c | 55 +++++++++++++++++++++++++++----------- 1 file changed, 39 insertions(+), 16 deletions(-) -- 2.17.1
