Subject: [PATCH] drivers: media: i2c: imx296,imx477: Configure tigger_mode
|
|
every time
|
|
|
|
Don't assume the camera has been reset each time we start streaming,
|
|
but always write registers relating to trigger_mode, even in mode 0.
|
|
|
|
IMX477: Stop driving XVS on stop streaming, to avoid spurious pulses.
