+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>;};
