+* Samsung Audio Subsystem Clock Controller
+
+The Samsung Audio Subsystem clock controller generates and supplies clocks
+to Audio Subsystem block available in the S5PV210 and compatible SoCs.
+
+Required Properties:
+
+- compatible: should be "samsung,s5pv210-audss-clock".
+- reg: physical base address and length of the controller's register set.
+
+- #clock-cells: should be 1.
+
+- clocks:
+  - hclk: AHB bus clock of the Audio Subsystem.
+  - xxti: Optional fixed rate PLL reference clock, parent of mout_audss. If
+    not specified (i.e. xusbxti is used for PLL reference), it is fixed to
+    a clock named "xxti".
+  - fout_epll: Input PLL to the AudioSS block, parent of mout_audss.
+  - iiscdclk0: Optional external i2s clock, parent of mout_i2s. If not
+    specified, it is fixed to a clock named "iiscdclk0".
+  - sclk_audio0: Audio bus clock, parent of mout_i2s.
+
+- clock-names: Aliases for the above clocks. They should be "hclk",
+  "xxti", "fout_epll", "iiscdclk0", and "sclk_audio0" respectively.
+
+All available clocks are defined as preprocessor macros in
+dt-bindings/clock/s5pv210-audss-clk.h header and can be used in device
+tree sources.
+
+Example: Clock controller node.
+
+	clk_audss: clock-controller@c0900000 {
+		compatible = "samsung,s5pv210-audss-clock";
+		reg = <0xc0900000 0x1000>;

+		clocks = <&clocks DOUT_HCLKP>, <&xxti>,
+				<&clocks FOUT_EPLL>, <&clocks SCLK_AUDIO0>;
+	};
+
+Example: I2S controller node that consumes the clock generated by the clock
+	 controller. Refer to the standard clock bindings for information
+         about 'clocks' and 'clock-names' property.
+
+	i2s0: i2s@03830000 {

+* Samsung S5P6442/S5PC110/S5PV210 Clock Controller
+
+Samsung S5P6442, S5PC110 and S5PV210 SoCs contain integrated clock
+controller, which generates and supplies clock to various controllers
+within the SoC.
+
+Required Properties:
+
+- compatible: should be one of following:
+	- "samsung,s5pv210-clock" : for clock controller of Samsung
+	  S5PC110/S5PV210 SoCs,
+	- "samsung,s5p6442-clock" : for clock controller of Samsung
+	  S5P6442 SoC.
+
+- reg: physical base address of the controller and length of memory mapped
+  region.
+
+- #clock-cells: should be 1.
+
+All available clocks are defined as preprocessor macros in
+dt-bindings/clock/s5pv210.h header and can be used in device tree sources.
+
+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:
+ - "xxti": external crystal oscillator connected to XXTI and XXTO pins of
+the SoC,
+ - "xusbxti": external crystal oscillator connected to XUSBXTI and XUSBXTO
+pins of the SoC,
+
+A subset of above clocks available on given board shall be specified in
+board device tree, including the system base clock, as selected by XOM[0]
+pin of the SoC. Refer to generic fixed rate clock bindings
+documentation[1] for more information how to specify these clocks.
+
+[1] Documentation/devicetree/bindings/clock/fixed-clock.txt
+
+Example: Clock controller node:
+
+	clock: clock-controller@7e00f000 {
+		compatible = "samsung,s5pv210-clock";
+		reg = <0x7e00f000 0x1000>;
+		#clock-cells = <1>;
+	};
+
+Example: Required external clocks:
+
+	xxti: clock-xxti {
+		compatible = "fixed-clock";
+		clock-output-names = "xxti";
+		clock-frequency = <24000000>;
+		#clock-cells = <0>;
+	};
+
+	xusbxti: clock-xusbxti {
+		compatible = "fixed-clock";
+		clock-output-names = "xusbxti";
+		clock-frequency = <24000000>;
+		#clock-cells = <0>;
+	};
+
+Example: UART controller node that consumes the clock generated by the clock
+  controller (refer to the standard clock bindings for information about
+  "clocks" and "clock-names" properties):
+
+	uart0: serial@e2900000 {
+		compatible = "samsung,s5pv210-uart";
+		reg = <0xe2900000 0x400>;
+		interrupt-parent = <&vic1>;
+		interrupts = <10>;
+		clock-names = "uart", "clk_uart_baud0",
+				"clk_uart_baud1";
+		clocks = <&clocks UART0>, <&clocks UART0>,
+				<&clocks SCLK_UART0>;
+		status = "disabled";
