From 76cc1cc9eb74bdfcce54a9b005155452e87e7168 Mon Sep 17 00:00:00 2001 From: Jani Nikula Date: Mon, 19 Sep 2016 15:02:28 +0300 Subject: [PATCH] drm/i915/dsi: run backlight on/off sequences in panel enable/disable hooks MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Based on the documentation alone, it's anyone's guess when exactly we should be running these sequences. Add them where it feels logical. The drm panel hooks don't currently offer us more granularity anyway.
