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 v2: - Rename ov5640_reset to ov5640_powerup_sequence to match datasheet - Remove the check for reset_gpio so that appropriate delays are honored when using only the pwdn_gpio - Remove redundant call to ov5640_power - Add 5ms delay after SW PWUP used in ov5640_set_stream_dvp() Jai Luthra (1): media: ov5640: Handle delays when no reset_gpio set Nishanth Menon (2): media: ov5640: Honor RESETB to SMBUS time t4 in init_setting media: ov5640: Honor power on time in init_setting drivers/media/i2c/ov5640.c | 35 ++++++++++++++++++++++++----------- 1 file changed, 24 insertions(+), 11 deletions(-) -- 2.17.1
