Subject: media: i2c: ov9282: Remove pixel rate from mode definition
X-Git-Tag: v6.6.17~5419^2~315
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=f15b0612c031827f1d0b9bd5626f7465bd15fac5;p=platform%2Fkernel%2Flinux-rpi.git

media: i2c: ov9282: Remove pixel rate from mode definition

The pixel rate is determined by the PLL setup in the common
registers, not by the mode specific registers, therefore
remove it from the mode definition and define it for all modes.
