From 215f34a55c4b00a7c7b3529d05d579295190c5cd Mon Sep 17 00:00:00 2001 From: Thierry Reding Date: Fri, 14 Mar 2014 12:03:47 +0100 Subject: [PATCH] drm/panel: simple: Allow GPIO accesses to sleep The enable GPIO for panels may be provided by GPIO expanders on slow busses (such as I2C), and therefore toggling the GPIO may sleep. Since these accesses don't happen in interrupt context, use the *_cansleep() variants of the GPIO API.
