Subject: [PATCH] media: i2c: imx290: Convert V4L2_CID_HBLANK to
|
|
read/write
|
|
|
|
Should be upstream commit 8cab2bd86307
|
|
|
|
The driver exposed V4L2_CID_HBLANK as a read only control to allow
|
|
for exposure calculations and determination of the frame rate.
|
|
|
|
Convert to a read/write control so that the frame rate can be
|
|
controlled.
