Subject: [PATCH v4 1/5] Documentation: tps65912: Add DT bindings for the TPS65912 PMIC
The TPS65912 PMIC contains several regulators and a GPIO controller.
Add bindings for the TPS65912 PMIC.
Signed-off-by: Andrew F. Davis <afd@...com>

+* TPS65912 GPIO Controller bindings
+
+Required properties:
+ - compatible : Should be "ti,tps65912-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 values.

+Example:
+

+Required properties:
