Merge tag 'clk-v4.9-samsung' of git://linuxtv.org/snawrocki/samsung into clk-next 

Pull samsung clk driver updates from Sylwester Nawrocki:

In addition to a few clean up and code consolidation patches this
includes:
- addition of sound subsystem related clocks for Exynos5410 SoC
  (EPLL, PDMA) and support for "samsung,exynos5410-audss-clock"
  compatible in the clk-exynos-audss driver,
- addition of DRAM controller related clocks for exynos5420,
- MAINTAINERS update adding Chanwoo Choi as the Samsung SoC
  clock drivers co-maintainer.

* tag 'clk-v4.9-samsung' of git://linuxtv.org/snawrocki/samsung:
  clk: samsung: Add support for EPLL on exynos5410
  clk: samsung: clk-exynos-audss: Whitespace and debug trace cleanup
  clk: samsung: clk-exynos-audss: Add exynos5410 compatible

- #clock-cells: should be 1.
- clocks: should contain an entry specifying the root clock from external
oscillator supplied through XXTI or XusbXTI pin. This clock should be
defined using standard clock bindings with "fin_pll" clock-output-name.
That clock is being passed internally to the 9 PLLs.
All available clocks are defined as preprocessor macros in
dt-bindings/clock/exynos5410.h header and can be used in device
tree sources.
External clock:
There is clock that is generated outside the SoC. It
is expected that it is defined using standard clock bindings
with following clock-output-name:
- "fin_pll" - PLL input clock from XXTI
Example 1: An example of a clock controller node is listed below.
fin_pll: xxti {
compatible = "fixed-clock";
clock-frequency = <24000000>;
clock-output-names = "fin_pll";
#clock-cells = <0>;
};
clock: clock-controller@0x10010000 {
compatible = "samsung,exynos5410-clock";
reg = <0x10010000 0x30000>;
#clock-cells = <1>;
clocks = <&fin_pll>;
};
Example 2: UART controller node that consumes the clock generated by the clock
