Subject: [PATCH v7 1/5] media: i2c: imx334: modify link frequency as for the configureation

From: Shravan Chippa <shravan.chippa@...rochip.com>

Currently imx334 sensor driver is configured for 1782Mbps/lane for
3840x2160@60 resolution with reqired reg mode values but if we run the
command "v4l2-ctl --all -d /dev/v4l-subdevX" it is showing incorrect link
frequeny, This is because of the incorrect value of IMX334_LINK_FREQ
witch is 891000000. it should be 1782000000.

In general with the value of 891000000 link frequency it is not possible
to configure 3840x2160@60 resolution.

Fixes: 9746b11715c3 ("media: i2c: Add imx334 camera sensor driver")
