Device-Tree binding for regmap

The endianness mode of CPU & Device scenarios:

Index     Device     Endianness properties

---------------------------------------------------

1         BE         'big-endian'

2         LE         'little-endian'

For one device driver, which will run in different scenarios above

on different SoCs using the devicetree, we need one way to simplify

this.

Required properties:

- {big,little}-endian: these are boolean properties, if absent

  meaning that the CPU and the Device are in the same endianness mode,

  these properties are for register values and all the buffers only.

Examples:

Scenario 1 : CPU in LE mode & device in LE mode.

dev: dev@40031000 {

	      compatible = "name";

	      reg = <0x40031000 0x1000>;

	      ...

};

Scenario 2 : CPU in LE mode & device in BE mode.

dev: dev@40031000 {

	      compatible = "name";

	      reg = <0x40031000 0x1000>;

	      ...

	      big-endian;

};

Scenario 3 : CPU in BE mode & device in BE mode.

dev: dev@40031000 {

	      compatible = "name";

	      reg = <0x40031000 0x1000>;

	      ...

};

Scenario 4 : CPU in BE mode & device in LE mode.

dev: dev@40031000 {

	      compatible = "name";

	      reg = <0x40031000 0x1000>;

	      ...

	      little-endian;

};

Analog Devices SSM2602, SSM2603 and SSM2604 I2S audio CODEC devices

SSM2602 support both I2C and SPI as the configuration interface,

the selection is made by the MODE strap-in pin.

SSM2603 and SSM2604 only support I2C as the configuration interface.

Required properties:

  - compatible : One of "adi,ssm2602", "adi,ssm2603" or "adi,ssm2604"

  - reg : the I2C address of the device for I2C, the chip select

          number for SPI.

 Example:

	ssm2602: ssm2602@1a {

		compatible = "adi,ssm2602";

		reg = <0x1a>;

	};

CS35L32 audio CODEC

Required properties:

  - compatible : "cirrus,cs35l32"

  - reg : the I2C address of the device for I2C. Address is determined by the level

  of the AD0 pin. Level 0 is 0x40 while Level 1 is 0x41.

  - VA-supply, VP-supply : power supplies for the device,

  as covered in Documentation/devicetree/bindings/regulator/regulator.txt.

Optional properties:

  - reset-gpios : a GPIO spec for the reset pin. If specified, it will be

  deasserted before communication to the codec starts.

  - cirrus,boost-manager : Boost voltage control.

  0 = Automatically managed.  Boost-converter output voltage is the higher

  of the two: Class G or adaptive LED voltage.

  1 = Automatically managed irrespective of audio, adapting for low-power

  dissipation when LEDs are ON, and operating in Fixed-Boost Bypass Mode

  if LEDs are OFF (VBST = VP).

  2 = (Default) Boost voltage fixed in Bypass Mode (VBST = VP).

  3 = Boost voltage fixed at 5 V.

  - cirrus,sdout-datacfg : Data configuration for dual CS35L32 applications only.

  Determines the data packed in a two-CS35L32 configuration.

  0 = Left/right channels VMON[11:0], IMON[11:0], VPMON[7:0].

  1 = Left/right channels VMON[11:0], IMON[11:0], STATUS.

  2 = (Default) left/right channels VMON[15:0], IMON [15:0].

  3 = Left/right channels VPMON[7:0], STATUS.

  - cirrus,sdout-share : SDOUT sharing. Determines whether one or two CS35L32

  devices are on board sharing SDOUT.

  0 = (Default) One IC.

  1 = Two IC's.

  - cirrus,battery-recovery : Low battery nominal recovery threshold, rising VP.

  0 = 3.1V

  1 = 3.2V

  2 = 3.3V (Default)

  3 = 3.4V

  - cirrus,battery-threshold : Low battery nominal threshold, falling VP.

  0 = 3.1V

  1 = 3.2V

  2 = 3.3V

  3 = 3.4V (Default)

  4 = 3.5V

  5 = 3.6V

Example:

codec: codec@40 {

	compatible = "cirrus,cs35l32";

	reg = <0x40>;

	reset-gpios = <&gpio 10 0>;

	cirrus,boost-manager = <0x03>;

	cirrus,sdout-datacfg = <0x02>;

	VA-supply = <&reg_audio>;

};
