[PATCH 01/11] drm/exynos: split display's .dpms() into .enable() and .disable()
Gustavo Padovan
gustavo at padovan.org
Mon Aug 10 17:37:04 PDT 2015
From: Gustavo Padovan <gustavo.padovan at collabora.co.uk>
The DRM Core doesn't have a dpms() operation anymore, everything
now is enable() or disable().
Signed-off-by: Gustavo Padovan <gustavo.padovan at collabora.co.uk>

v2: set dp->dpms_mode after enable/disable
