Subject: [PATCH] media: i2c: imx290: Add support for the mono sensor
|
|
variant
|
|
|
|
Should be upstream commit 9bf52c7136d1
|
|
|
|
The IMX290 module is available as either mono or colour (Bayer).
|
|
|
|
Update the driver so that it can advertise the correct mono
|
|
formats instead of the colour ones.
