Subject: [PATCH] media: i2c: imx290: Replace V4L2_CID_GAIN with
|
||
|
|
V4L2_CID_ANALOGUE_GAIN
|
||
|
|
|
||
|
|
Most software (including libcamera) requires V4L2_CID_ANALOGUE_GAIN,
|
||
|
|
not V4L2_CID_GAIN.
|
||
|
|
|
||
|
|
The range for the control is 0 to 100 for which the sensor uses only
|
||
|
|
analogue gain; higher values would involve digital gain which this
|
||
|
|
control should not apply.
|
||
