+Texas Instruments TAS2770 Smart PA
+
+The TAS2770 is a mono, digital input Class-D audio amplifier optimized for
+efficiently driving high peak power into small loudspeakers.
+Integrated speaker voltage and current sense provides for
+real time monitoring of loudspeaker behavior.
+
+Required properties:
+
+ - compatible:	   - Should contain "ti,tas2770".
+ - reg:		       - The i2c address. Should contain <0x4c>, <0x4d>,<0x4e>, or <0x4f>.
+ - #address-cells  - Should be <1>.
+ - #size-cells     - Should be <0>.
+ - ti,asi-format:  - Sets TDM RX capture edge. 0->Rising; 1->Falling.
+ - ti,left-slot:   - Sets TDM RX left time slots.
+ - ti,right-slot:  - Sets TDM RX right time slots.
+ - ti,imon-slot-no:- TDM TX current sense time slot.
+ - ti,vmon-slot-no:- TDM TX voltage sense time slot.
+
+Optional properties:
+
+ - reset-gpio:	Reset GPIO number of left device.
+ - irq-gpio:  IRQ GPIO number of left device.
+
+Examples:
+
+    tas2770@4c {
+                compatible = "ti,tas2770";
+                reg = <0x4c>;
+                reset-gpio = <&gpio15 1 GPIO_ACTIVE_LOW>;
+                irq-gpio = <&gpio16 1 GPIO_ACTIVE_LOW>;
+                ti,asi-format = <0>;
+                ti,left-slot = <0>;
+                ti,right-slot = <1>;
+                ti,imon-slot-no = <0>;
+                ti,vmon-slot-no = <2>;
+        };
