ASoC: More updates for v3.14

A few more updates for v3.14 since the last set, highlights include:

 - Lots of DMA updates from Lars-Peter
 - Improvements to the constraints handling code from Lars-Peter
 - A very helpful conversion of the TWL4030 driver to regmap from Peter
 - A new driver for the Freescale ESAI controller from Nicolin Chen
 - Conversion of some of the drivers to use params_width()

+Freescale Enhanced Serial Audio Interface (ESAI) Controller
+
+The Enhanced Serial Audio Interface (ESAI) provides a full-duplex serial port
+for serial communication with a variety of serial devices, including industry
+standard codecs, Sony/Phillips Digital Interface (S/PDIF) transceivers, and
+other DSPs. It has up to six transmitters and four receivers.
+
+Required properties:
+
+  - compatible : Compatible list, must contain "fsl,imx35-esai".
+
+  - reg : Offset and length of the register set for the device.
+
+  - interrupts : Contains the spdif interrupt.
+
+  - dmas : Generic dma devicetree binding as described in
+  Documentation/devicetree/bindings/dma/dma.txt.
+
+  - dma-names : Two dmas have to be defined, "tx" and "rx".
+
+  - clocks: Contains an entry for each entry in clock-names.
+
+  - clock-names : Includes the following entries:
+	"core"		The core clock used to access registers
+	"extal"		The esai baud clock for esai controller used to derive
+			HCK, SCK and FS.
+	"fsys"		The system clock derived from ahb clock used to derive
+			HCK, SCK and FS.
+
+  - fsl,fifo-depth: The number of elements in the transmit and receive FIFOs.
+    This number is the maximum allowed value for TFCR[TFWM] or RFCR[RFWM].
+
+  - fsl,esai-synchronous: This is a boolean property. If present, indicating
+    that ESAI would work in the synchronous mode, which means all the settings
+    for Receiving would be duplicated from Transmition related registers.
+
+Example:
+
+esai: esai@02024000 {
+	compatible = "fsl,imx35-esai";
+	reg = <0x02024000 0x4000>;
+	interrupts = <0 51 0x04>;
+	clocks = <&clks 208>, <&clks 118>, <&clks 208>;
+	clock-names = "core", "extal", "fsys";
+	dmas = <&sdma 23 21 0>, <&sdma 24 21 0>;
+	dma-names = "rx", "tx";
+	fsl,fifo-depth = <128>;
+	fsl,esai-synchronous;
+	status = "disabled";
+};
