Subject: [media] exynos4-is: Add support for all required clocks
Author:  Marek Szyprowski <m.szyprow...@samsung.com>
Date:    Wed Aug 31 10:25:16 2016 -0300

This patch adds 3 more clocks to Exynos4 ISP driver. Enabling them is
needed to make the hardware operational. Till now it worked only because
those clocks were registered with IGNORE_UNUSED flag and were enabled
by default after SoC reset.
