    1 Texas Instruments TAS2770 Smart PA
    2 
    3 The TAS2770 is a mono, digital input Class-D audio amplifier optimized for
    4 efficiently driving high peak power into small loudspeakers.
    5 Integrated speaker voltage and current sense provides for
    6 real time monitoring of loudspeaker behavior.
    7 
    8 Required properties:
    9 
   10  - compatible:     - Should contain "ti,tas2770".
   11  - reg:                - The i2c address. Should contain <0x4c>, <0x4d>,<0x4e>, or <0x4f>.
   12  - #address-cells  - Should be <1>.
   13  - #size-cells     - Should be <0>.
   14  - ti,asi-format:  - Sets TDM RX capture edge. 0->Rising; 1->Falling.
   15  - ti,imon-slot-no:- TDM TX current sense time slot.
   16  - ti,vmon-slot-no:- TDM TX voltage sense time slot.
   17 
   18 Optional properties:
   19 
   20 - interrupt-parent: the phandle to the interrupt controller which provides
   21                      the interrupt.
   22 - interrupts: interrupt specification for data-ready.
   23 
   24 Examples:
   25 
   26     tas2770@4c {
   27                 compatible = "ti,tas2770";
   28                 reg = <0x4c>;
   29                 #address-cells = <1>;
   30                 #size-cells = <0>;
   31                 interrupt-parent = <&msm_gpio>;
   32                 interrupts = <97 0>;
   33                 ti,asi-format = <0>;
   34                 ti,imon-slot-no = <0>;
   35                 ti,vmon-slot-no = <2>;
   36         };
