[PATCH 5/9] dt-bindings: pinctrl: meson: update gpio dt-bindings

From: jbrunet@baylibre.com (Jerome Brunet)
Date: 2016-10-19 15:37:11
Also in: linux-amlogic, linux-devicetree, linux-gpio, lkml
Subsystem: open firmware and flattened device tree bindings, pin control subsystem, the rest · Maintainers: Rob Herring, Krzysztof Kozlowski, Conor Dooley, Linus Walleij, Linus Torvalds

Add description for the interrupt-parent property of the gpio sub-node
If provided here, this property must be a phandle to an interrupt
controller suitable for meson pinctrl, like the meson gpio interrupt
controller.
