[PATCH] dt-bindings: input: Convert TI Palmas Power Button to DT schema

[PATCH] dt-bindings: input: Convert TI Palmas Power Button to DT schema

[Eduard Bostina]

Convert the Texas Instruments Palmas power button bindings
to DT schema.

During the conversion, 'wakeup-source' was added.
It was missing from the original text binding but is actively
used by in-tree boards.

-Texas Instruments Palmas family power button module
-
-This module is part of the Palmas family of PMICs. For more details
-about the whole chip see:
-Documentation/devicetree/bindings/mfd/palmas.txt.
-
-This module provides a simple power button event via an Interrupt.
-
-Required properties:
-- compatible: should be one of the following
-   - "ti,palmas-pwrbutton": For Palmas compatible power on button
-- interrupts: Interrupt number of power button submodule on device.
-
-Optional Properties:
-
-- ti,palmas-long-press-seconds: Duration in seconds which the power
-  button should be kept pressed for Palmas to power off automatically.
-  NOTE: This depends on OTP support and POWERHOLD signal configuration
-  on platform. Valid values are 6, 8, 10 and 12.
-- ti,palmas-pwron-debounce-milli-seconds: Duration in milliseconds
-  which the power button should be kept pressed for Palmas to register
-  a press for debouncing purposes. NOTE: This depends on specific
-  Palmas variation capability. Valid values are 15, 100, 500 and 1000.
-
-Example:
-
-&palmas {
-	palmas_pwr_button: pwrbutton {
-		compatible = "ti,palmas-pwrbutton";
-		interrupt-parent = <&tps659038>;
-		interrupts = <1 IRQ_TYPE_EDGE_FALLING>;
-		ti,palmas-long-press-seconds = <12>;
-		ti,palmas-pwron-debounce-milli-seconds = <15>;
-	};
-};
