From 5318f18d2c002f505054b90bb95ba7c53532eedf Mon Sep 17 00:00:00 2001 From: Gabriel Huau Date: Mon, 25 May 2015 22:27:37 -0700 Subject: x86: gpio: add pinctrl support from the device tree Every pin can be configured now from the device tree. A dt-bindings has been added to describe the different property available.
