Subject: [PATCH 1/4] Documentation: tps65086: Add DT bindings for the TPS65086 PMIC
The TPS65086 PMIC contains several regulators and a GPO controller.
Add bindings for the TPS65086 PMIC.
Signed-off-by: Andrew F. Davis <afd@...com>

+* TPS65086 regulator bindings
+
+Required properties:

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

+
+Optional properties:
+ - Per-regulator optional properties are defined in regulator.txt
+ - ti,regulator-step-size-25mv : This is applicable for buck[1,2,6].
