[PATCH v2 02/19] dt-bindings: gpio: Add ASPEED constants
From: joel@jms.id.au (Joel Stanley)
Date: 2017-12-15 06:25:29
Also in:
linux-aspeed, linux-devicetree, lkml
Subsystem:
gpio subsystem, open firmware and flattened device tree bindings, the rest · Maintainers:
Linus Walleij, Bartosz Golaszewski, Rob Herring, Krzysztof Kozlowski, Conor Dooley, Linus Torvalds
These are used to by the device tree to map pin numbers to constants required by the GPIO bindings.
