+* Samsung Audio Subsystem Clock Controller
+
+The Samsung Audio Subsystem clock controller generates and supplies clocks
+to Audio Subsystem block available in the S5PV210 and Exynos SoCs. The clock
+binding described here is applicable to all SoC's in Exynos family.
+
+Required Properties:
+
+- compatible: should be one of the following:
+ - "samsung,exynos4210-audss-clock" - controller compatible with all Exynos4 SoCs.
+ - "samsung,exynos5250-audss-clock" - controller compatible with all Exynos5 SoCs.
+
+- reg: physical base address and length of the controller's register set.
+
+- #clock-cells: should be 1.
+
+The following is the list of clocks generated by the controller. Each clock is
+assigned an identifier and client nodes use this identifier to specify the
+clock which they consume. Some of the clocks are available only on a particular
+Exynos4 SoC and this is specified where applicable.
+
+Provided clocks:
