arm: tegra: ventana: deselect pca9546 i2c mux channel on exit
On ventana, pca9546 is used as a mux for 0v2710/ov5650 camera sensors. With UJA0H14 version of ov5650 sensor, it is observed that pca9546 driver incorrectly caches last channel when VDDIO_CAM is toggled while enabling/disabling tegra camera. Deselect i2c mux channel on exit so that i2c mux is correctly configured with new mux channel. BUG 812134 (cherry picked from commit 2d62e589c0bd933db846d4b8f9fe4f2116bef8ad) Change-Id: Id249bbeb33c370b8fc5360af33bdefecfd62a48a Reviewed-on: http://git-master/r/29811 Tested-by: Nitin Kumbhar <nkumbhar@nvidia.com> Reviewed-by: Pritesh Raithatha <praithatha@nvidia.com> Reviewed-by: Erik M Lilliebjerg <elilliebjerg@nvidia.com> Reviewed-by: Bharat Nihalani <bnihalani@nvidia.com>
