From ae80d64ee8c88b77c58254bcdc5c0981faab672d Mon Sep 17 00:00:00 2001 From: Javier Martinez Canillas Date: Tue, 1 Sep 2015 10:46:15 +0200 Subject: [PATCH] Documentation: gpio: Explain that -gpio is also supported The GPIO documentation mentions that GPIOs are mapped by defining a -gpios property in the consumer device's node but a -gpio sufix is also supported after commit: dd34c37aa3e8 ("gpio: of: Allow -gpio suffix for property names") Update the documentation to match the implementation.
