+* Samsung Exynos7 Clock Controller
+
+Exynos7 clock controller has various blocks which are instantiated
+independently from the device-tree. These clock controllers
+generate and supply clocks to various hardware blocks within
+the SoC.

+
+External clocks:
+
+There are several clocks that are generated outside the SoC. It
+is expected that they are defined using standard clock bindings
+with following clock-output-names:
+
+ - "fin_pll" - PLL input clock from XXTI
+
+Required Properties for Clock Controller:
+
+ - compatible: clock controllers will use one of the following
+ compatible strings to indicate the clock controller
+ functionality.

+ - "samsung,exynos7-clock-peris"
+ - "samsung,exynos7-clock-fsys0"
