Subject: [PATCH v3 0/5] Introduce support for Exynos7870 clocks and PMU

Add a CMU driver for Exynos7870 devices. It handles the following
clock banks:
 * CMU_MIF
 * CMU_DISPAUD
 * CMU_FSYS
 * CMU_G3D
 * CMU_ISP
 * CMU_MFCMSCL
 * CMU_PERI

It also documents Exynos7870 PMU's compatible, and adds a CLKOUT driver
which depends on the compatible. The CLKOUT driver manages clocks from
PMU_DEBUG.

This patch series is a part of Exynos7870 upstreaming.
