From b80fbd4bcba11a99bcd1bc4cd435f52ccbcd653a Mon Sep 17 00:00:00 2001 From: Dave Stevenson Date: Tue, 15 Jun 2021 18:56:33 +0100 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.
