Subject: [PATCH] media: i2c: imx290: VMAX is mode dependent
|
|
|
|
Should be upstream commit b3aa351ea88a
|
|
|
|
The default VMAX for 60fps in 720p mode is 750 according to the
|
|
datasheet, however the driver always left it at 1125 thereby stopping
|
|
60fps being achieved.
|
|
|
|
Make VMAX (and therefore V4L2_CID_VBLANK) mode dependent so that 720p60
|
|
can be achieved.
