			  it. This property is optional depending on the SoC

			  design.

Imagination Technologies I2S Input Controller

Required Properties:

  - compatible : Compatible list, must contain "img,i2s-in"

  - #sound-dai-cells : Must be equal to 0

  - reg : Offset and length of the register set for the device

  - clocks : Contains an entry for each entry in clock-names

  - clock-names : Must include the following entry:

	"sys"	The system clock

  - dmas: Contains an entry for each entry in dma-names.

  - dma-names: Must include the following entry:

	"rx"	Single DMA channel used by all active I2S channels

  - img,i2s-channels : Number of I2S channels instantiated in the I2S in block

Optional Properties:

  - interrupts : Contains the I2S in interrupts. Depending on

	the configuration, there may be no interrupts, one interrupt,

	or an interrupt per I2S channel. For the case where there is

	one interrupt per channel, the interrupts should be listed

	in ascending channel order

  - resets: Contains a phandle to the I2S in reset signal

  - reset-names: Contains the reset signal name "rst"

Example:

i2s_in: i2s-in@18100800 {

	compatible = "img,i2s-in";

	reg = <0x18100800 0x200>;

	interrupts = <GIC_SHARED 7 IRQ_TYPE_LEVEL_HIGH>;

	dmas = <&mdc 30 0xffffffff 0>;

	dma-names = "rx";

	clocks = <&cr_periph SYS_CLK_I2S_IN>;

	clock-names = "sys";

	img,i2s-channels = <6>;

	#sound-dai-cells = <0>;

};

Imagination Technologies I2S Output Controller

Required Properties:

  - compatible : Compatible list, must contain "img,i2s-out"

  - #sound-dai-cells : Must be equal to 0

  - reg : Offset and length of the register set for the device

  - clocks : Contains an entry for each entry in clock-names

  - clock-names : Must include the following entries:

	"sys"	The system clock

	"ref"	The reference clock

  - dmas: Contains an entry for each entry in dma-names.

  - dma-names: Must include the following entry:

	"tx"	Single DMA channel used by all active I2S channels

  - img,i2s-channels : Number of I2S channels instantiated in the I2S out block

  - resets: Contains a phandle to the I2S out reset signal

  - reset-names: Contains the reset signal name "rst"

Optional Properties:

  - interrupts : Contains the I2S out interrupts. Depending on

	the configuration, there may be no interrupts, one interrupt,

	or an interrupt per I2S channel. For the case where there is

	one interrupt per channel, the interrupts should be listed

	in ascending channel order

Example:

i2s_out: i2s-out@18100A00 {

	compatible = "img,i2s-out";

	reg = <0x18100A00 0x200>;

	interrupts = <GIC_SHARED 13 IRQ_TYPE_LEVEL_HIGH>;

	dmas = <&mdc 23 0xffffffff 0>;

	clocks = <&cr_periph SYS_CLK_I2S_OUT>,

		 <&clk_core CLK_I2S>;

	clock-names = "sys", "ref";

	img,i2s-channels = <6>;

  - dma-names: Must include the following entry:

	"tx"

  - clocks : Contains an entry for each entry in clock-names.

  - clock-names : Includes the following entries:

	"sys"	The system clock

	"ref"	The reference clock

  - resets: Contains a phandle to the parallel out reset signal

  - reset-names: Contains the reset signal name "rst"

Optional Properties:

  - interrupts : Contains the parallel out interrupt, if present

Example:

parallel_out: parallel-out@18100C00 {

	compatible = "img,parallel-out";

	reg = <0x18100C00 0x100>;

	interrupts = <GIC_SHARED 19 IRQ_TYPE_LEVEL_HIGH>;
