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.

+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;
