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.
