* 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>;

		#clock-cells = <1>;

		clock-names = "hclk", "xxti",

				"fout_epll", "sclk_audio0";

		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 {

		/* ... */

		clock-names = "iis", "i2s_opclk0",

				"i2s_opclk1";

		clocks = <&clk_audss CLK_I2S>, <&clk_audss CLK_I2S>,

				<&clk_audss CLK_DOUT_AUD_BUS>;

		/* ... */

	};

* 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";

	};
