* 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:

Clock           ID      SoC (if specific)

mout_audss      0

mout_i2s        1

Example 1: An example of a clock controller node is listed below.

clock_audss: audss-clock-controller@3810000 {

	compatible = "samsung,exynos5250-audss-clock";

	reg = <0x03810000 0x0C>;

	#clock-cells = <1>;

};

Example 2: 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 {

	compatible = "samsung,i2s-v5";

	reg = <0x03830000 0x100>;

	dmas = <&pdma0 10

		&pdma0 9

		&pdma0 8>;

	dma-names = "tx", "rx", "tx-sec";

	clocks = <&clock_audss EXYNOS_I2S_BUS>,

	};

Clients

Required properties:

- dmas: Comma separated list of dma channel requests

- dma-names: Names of the aforementioned requested channels

Each dmas request consists of 4 cells:

  1. A phandle pointing to the DMA controller

  2. Device Type

  3. The DMA request line number (only when 'use fixed channel' is set)

  4. A 32bit mask specifying; mode, direction and endianess [NB: This list will grow]

        0x00000001: Mode:

                Logical channel when unset

                Physical channel when set

        0x00000002: Direction:

                Memory to Device when unset

                Device to Memory when set

        0x00000004: Endianess:

                Little endian when unset

                Big endian when set

        0x00000008: Use fixed channel:

                Use automatic channel selection when unset

                Use DMA request line number when set

Example:

	uart@80120000 {

		compatible = "arm,pl011", "arm,primecell";

		reg = <0x80120000 0x1000>;

		interrupts = <0 11 0x4>;

		dmas = <&dma 13 0 0x2>, /* Logical - DevToMem */

Samsung S3C24XX GPIO Controller

Required properties:

- compatible: Compatible property value should be "samsung,s3c24xx-gpio".

- reg: Physical base address of the controller and length of memory mapped

  region.

- #gpio-cells: Should be 3. The syntax of the gpio specifier used by client nodes

  should be the following with values derived from the SoC user manual.

     <[phandle of the gpio controller node]

      [pin number within the gpio controller]

      [mux function]

      [flags and pull up/down]

  Values for gpio specifier:

  - Pin number: depending on the controller a number from 0 up to 15.

  - Mux function: Depending on the SoC and the gpio bank the gpio can be set

                  as input, output or a special function

  - Flags and Pull Up/Down: the values to use differ for the individual SoCs

                    example S3C2416/S3C2450:

                            0 - Pull Up/Down Disabled.

                            1 - Pull Down Enabled.

                            2 - Pull Up Enabled.

          Bit 16 (0x00010000) - Input is active low.

  Consult the user manual for the correct values of Mux and Pull Up/Down.
