Subject: [PATCH] media: i2c: imx258: Make V4L2_CID_VBLANK
|
|
configurable.
|
|
|
|
The values and ranges of V4L2_CID_VBLANK are all computed,
|
|
so there is no reason for it to be a read only control.
|
|
Remove the register values from the mode lists, add the
|
|
handler, and remove the read only flag.
