Subject: [PATCH 1/2] dt-bindings: tas2770: Convert tas2770 binding to yaml
Convert the tas2770 binding to yaml format.
Add in the reset-gpio to the binding as it is in the code but not
documented in the binding.
Signed-off-by: Dan Murphy <dmurphy@...com>

-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>;
