From 0d56bf0b65e6930ea00060d4107414b8d74c9055 Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Thu, 24 Apr 2014 23:54:37 +0200 Subject: [PATCH] drm/i915: Make encoder->mode_set callbacks optional For a bunch of reasons we want to move away from the ->mode_set callbacks: All hw state setup needs to move into ->enable hooks (so that DOMS can do runtime pm) and all the configuration setup needs to move into the compute_config functions. To start with this make the enocer->mode_set callback optional.
