[PATCH] gpio-exar: Use correct property prefix and document bindings
From: Jan Kiszka <hidden>
Date: 2017-07-13 06:44:38
Also in:
linux-gpio, lkml
Subsystem:
8250/16?50 (and clone uarts) serial driver, gpio subsystem, open firmware and flattened device tree bindings, the rest, tty layer and serial drivers · Maintainers:
Greg Kroah-Hartman, Linus Walleij, Bartosz Golaszewski, Rob Herring, Krzysztof Kozlowski, Conor Dooley, Linus Torvalds, Jiri Slaby
The device-specific property should be prefixed with the vendor name Change this and document the bindings of this platform device.
