[PATCH 1/4] Documentation: tps65086: Add DT bindings for the TPS65086 PMIC

[Andrew F. Davis]

The TPS65086 PMIC contains several regulators and a GPO controller.
Add bindings for the TPS65086 PMIC.

+* TPS65086 GPO Controller bindings

+Required properties:
+ - compatible		: Should be "ti,tps65086-gpio".
+ - gpio-controller	: Marks the device node as a GPIO Controller.
+ - #gpio-cells		: Should be two.  The first cell is the pin number
+			  and the second cell is used to specify flags.
+			  See include/dt-bindings/gpio/gpio.h for possible

+		#gpio-cells = <2>;

+Required properties:

+ - #interrupt-cells	: The number of cells to describe an IRQ, this

+Required properties:

+ - list of regulators provided by this controller, must be named

+     swb[1-2], and vtt.
+
+Optional properties:
+ - Per-regulator optional properties are defined in regulator.txt
+ - ti,regulator-step-size-25mv	: This is applicable for buck[1,2,6].
+				  Set this if the regulator is factory
+				  set with a 25mv step voltage mapping.
+ - ti,regulator-decay		: This is applicable for buck[1-6].
