Subject: media: imx335: Fix active area height discrepency
X-Git-Tag: v6.10-rc1~135^2~190
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=81495a59baebab3fd8fd859a60dac7bf82d2b290;p=thirdparty%2Fkernel%2Flinux.git

media: imx335: Fix active area height discrepency

The imx335 reports a recommended pixel area of - 2592x1944.
The driver supported mode however limits it to height=1940.

Fix the height discrepency by correctly the value of height
(with updates to vblank and mode registers).

The IMX335_REG_HTRIMMING should also be corrected to the start
offset(i.e. 48) instead of chosing a abritrary crop start of 384.
