+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,imon-slot-no:- TDM TX current sense time slot.
+ - ti,vmon-slot-no:- TDM TX voltage sense time slot.
+
+Optional properties:
+
+- interrupt-parent: the phandle to the interrupt controller which provides
+ the interrupt.
+- interrupts: interrupt specification for data-ready.
+
+Examples:
+
+ tas2770@4c {
+ compatible = "ti,tas2770";
+ reg = <0x4c>;
+ #address-cells = <1>;
+ #size-cells = <0>;
+ interrupt-parent = <&msm_gpio>;
+ interrupts = <97 0>;
+ ti,asi-format = <0>;
+ ti,imon-slot-no = <0>;
+ ti,vmon-slot-no = <2>;
+ };
