+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>.
s/should/may
+ - #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.
You might want to use
- interrupt-parent: the phandle to the interrupt controller which provides
the interrupt.
- interrupts: interrupt specification for data-ready.
Instead of irq-gpio
+
+Examples:
+
+ tas2770@4c {
+ compatible = "ti,tas2770";
+ reg = <0x4c>;
Missing
#address-cells = <1>;
#size-cells = <0>;
+ 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>;
+ };
+
Suggestion to provide the URL to the data sheet.
