-* 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 SoCs 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 Exynos5250
- SoCs.

- SoCs.
- - "samsung,exynos5420-audss-clock" - controller compatible with Exynos5420
- SoCs.
-- reg: physical base address and length of the controller's register set.
-
-- #clock-cells: should be 1.
-
-- clocks:
- - pll_ref: Fixed rate PLL reference clock, parent of mout_audss. "fin_pll"
- is used if not specified.
- - pll_in: Input PLL to the AudioSS block, parent of mout_audss. "fout_epll"
