[PATCH V3] dt-bindings: input: pwm-beeper: convert to dt schema

[Peng Fan (OSS)]

From: Peng Fan <peng.fan@xxxxxxx>

Convert the binding doc to dt schema, and also fixed the
example from fixed-regulator to regulator-fixed.

Signed-off-by: Peng Fan <peng.fan@xxxxxxx>

 V3:
  Drop description for pwms
  Simplify description for amp-supply
  update beeper-hz range to 10-10000

 V2:
  License update
  Don't need to show providers
  Make example complete
  Decrease beeper hz
  Misc update

-* PWM beeper device tree bindings
-
-Registers a PWM device as beeper.
-
-Required properties:
-- compatible: should be "pwm-beeper"
-- pwms: phandle to the physical PWM device
-
-Optional properties:
-- amp-supply: phandle to a regulator that acts as an amplifier for the beeper
-- beeper-hz:  bell frequency in Hz
-
-Example:
-
-beeper_amp: amplifier {
-	compatible = "fixed-regulator";
-	gpios = <&gpio0 1 GPIO_ACTIVE_HIGH>;
-};
-
-beeper {
-	compatible = "pwm-beeper";
-	pwms = <&pwm0>;
-	amp-supply = <&beeper_amp>;
-};
