[PATCH v1 1/3] media: i2c: imx274: Fix Y_OUT_SIZE register setting

From: Sowjanya Komatineni
Date: Wed Jul 15 2020 - 00:23:27 EST


Current driver sets Y_OUT_SIZE to crop height + 8 and seeing long frame
errors on the receiver size as expected height on reciever is crop height.

As per Sony IMX274 Y_OUT_SIZE should be the height of effective
image output from the sensor which are the actual total lines
sent over MIPI CSI to receiver.

So, Y_OUT_SIZE should be same as crop height and this patch fixes it.
