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;

};

Freescale Generic ASoC Sound Card with ASRC support

The Freescale Generic ASoC Sound Card can be used, ideally, for all Freescale

SoCs connecting with external CODECs.

The idea of this generic sound card is a bit like ASoC Simple Card. However,

for Freescale SoCs (especially those released in recent years), most of them

have ASRC (Documentation/devicetree/bindings/sound/fsl,asrc.txt) inside. And

this is a specific feature that might be painstakingly controlled and merged

into the Simple Card.

So having this generic sound card allows all Freescale SoC users to benefit

from the simplification of a new card support and the capability of the wide

sample rates support through ASRC.

Note: The card is initially designed for those sound cards who use I2S and

      PCM DAI formats. However, it'll be also possible to support those non

      I2S/PCM type sound cards, such as S/PDIF audio and HDMI audio, as long

      as the driver has been properly upgraded.

The compatible list for this generic sound card currently:

 "fsl,imx-audio-cs42888"

 "fsl,imx-audio-wm8962"

 (compatible with Documentation/devicetree/bindings/sound/imx-audio-wm8962.txt)

 "fsl,imx-audio-sgtl5000"

 (compatible with Documentation/devicetree/bindings/sound/imx-audio-sgtl5000.txt)

Required properties:

  - compatible		: Contains one of entries in the compatible list.

  - model		: The user-visible name of this sound complex

  - audio-cpu		: The phandle of an CPU DAI controller

  - audio-codec		: The phandle of an audio codec

  - audio-routing	: A list of the connections between audio components.

			  Each entry is a pair of strings, the first being the

			  connection's sink, the second being the connection's

			  source. There're a few pre-designed board connectors:

			   * Line Out Jack

			   * Line In Jack

			   * Headphone Jack

			   * Mic Jack

			   * Ext Spk

			   * AMIC (stands for Analog Microphone Jack)

			   * DMIC (stands for Digital Microphone Jack)

			  Note: The "Mic Jack" and "AMIC" are redundant while

			        coexsiting in order to support the old bindings

				of wm8962 and sgtl5000.

Optional properties:

  - audio-asrc		: The phandle of ASRC. It can be absent if there's no

			  need to add ASRC support via DPCM.

Example:

sound-cs42888 {

	compatible = "fsl,imx-audio-cs42888";

	model = "cs42888-audio";

	audio-cpu = <&esai>;

	audio-asrc = <&asrc>;

	audio-codec = <&cs42888>;

	audio-routing =
