[PATCH v2 38/52] dt-bindings: w1: Convert 1-Wire GPIO binding to a schema

[Maxime Ripard]

Bitbanged 1-Wire buses are supported by Linux thanks to their device
tree binding.

Now that we have the DT validation in place, let's convert the device
tree bindings for that driver over to a YAML schema.

Changes from v1:
  - Changed additionalproperties to make sure all the other items in the
    schema are nodes

-Required properties:
-
- - compatible: "w1-gpio"
- - gpios: one or two GPIO specs:
-		- the first one is used as data I/O pin
-		- the second one is optional. If specified, it is used as
-		  enable pin for an external pin pullup.
-
-Optional properties:
-
- - linux,open-drain: if specified, the data pin is considered in
-		     open-drain mode.
-
-Also refer to the generic w1.txt document.

-Examples:
-
-	onewire {
-		compatible = "w1-gpio";
-		gpios = <&gpio 0 GPIO_ACTIVE_HIGH>;
-
-		battery {
-			// ...
-		};
-	};
