-Texas Instruments TAS2562 Smart PA
-
-The TAS2562 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:
- - #address-cells - Should be <1>.
- - #size-cells - Should be <0>.
- - compatible: - Should contain "ti,tas2562", "ti,tas2563".
- - reg: - The i2c address. Should be 0x4c, 0x4d, 0x4e or 0x4f.
- - ti,imon-slot-no:- TDM TX current sense time slot.
- - ti,vmon-slot-no:- TDM TX voltage sense time slot. This slot must always be
- greater then ti,imon-slot-no.
-
-Optional properties:
-- interrupt-parent: phandle to the interrupt controller which provides
- the interrupt.
-- interrupts: (GPIO) interrupt to which the chip is connected.
-- shut-down-gpio: GPIO used to control the state of the device.
-
-Examples:
-tas2562@4c {
- #address-cells = <1>;
- #size-cells = <0>;
- compatible = "ti,tas2562";
- reg = <0x4c>;
-
- interrupt-parent = <&gpio1>;
- interrupts = <14>;
-
- shut-down-gpio = <&gpio1 15 0>;
- ti,imon-slot-no = <0>;
- ti,vmon-slot-no = <1>;
-};
