Subject: [PATCH] drivers: media: imx296: Add standby delay during probe
|
2023-10-09 16:43:46 +00:00

|
|
|
Add a 2-5ms delay when coming out of standby and before reading the
|
|
|
|
|
sensor info register durning probe, as instructed by the datasheet. This
|
|
|
|
|
standby delay is already present when the sensor starts streaming.
