ASoC: Updates for v4.7 part 2

Really sorry about this late pull request.  It looks like at the time I
sent my pull request for v4.7 there was some conflict or other issue
which caused my script to stop merging the ASoC branches at some point
after the HDMI changes.

It's all specific driver updates, including:

 - New drivers for MAX98371 and TAS5720.
 - SPI support for TLV320AIC32x4.
 - TDM support for STI Uniperf IPs.

This code should all have been in -next prior to the merge window apart
from some fixes, it dropped out on the 18th.

Device-Tree binding for regmap



The endianness mode of CPU & Device scenarios:

Index     Device     Endianness properties

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

1         BE         'big-endian'

2         LE         'little-endian'

3	  Native     'native-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.

Devicetree binding for regmap



Optional properties:

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

  then the implementation will choose a default based on the device

  being controlled.  These properties are for register values and all

  the buffers only.  Native endian means that the CPU and device have

  the same endianness.



Examples:

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

dev: dev@40031000 {

	      compatible = "name";

	      reg = <0x40031000 0x1000>;

	      ...

};

   little-endian,

   big-endian,

   native-endian:	See common-properties.txt for a definition



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

dev: dev@40031000 {

	      compatible = "name";

	      reg = <0x40031000 0x1000>;

	      ...

	      big-endian;

};

Note:

Regmap defaults to little-endian register access on MMIO based

devices, this is by far the most common setting. On CPU

architectures that typically run big-endian operating systems

(e.g. PowerPC), registers can be defined as big-endian and must

be marked that way in the devicetree.



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

dev: dev@40031000 {

	      compatible = "name";

	      reg = <0x40031000 0x1000>;

	      ...

};

On SoCs that can be operated in both big-endian and little-endian

modes, with a single hardware switch controlling both the endianess

of the CPU and a byteswap for MMIO registers (e.g. many Broadcom MIPS

chips), "native-endian" is used to allow using the same device tree

blob in both cases.



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

Examples:

Scenario 1 : a register set in big-endian mode.

dev: dev@40031000 {

	      compatible = "name";

	      compatible = "syscon";

	      reg = <0x40031000 0x1000>;

	      big-endian;

	      ...

	      little-endian;

};
