From: Stephane Viau Date: Tue, 18 Nov 2014 17:49:48 +0000 (-0500) Subject: drm/msm/mdp5: introduce mdp5_cfg module X-Git-Tag: MMI-PSA29.97-13-9~10979^2~28^2~10 X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=2e362e1772b8978428f087007fc4d6c4990efd41;p=GitHub%2FMotorolaMobilityLLC%2Fkernel-slsi.git drm/msm/mdp5: introduce mdp5_cfg module The hardware configuration modification from a version to another is quite consequent. Introducing a configuration module (mdp5_cfg) may make things more clear and easier to access when a new hardware version comes up.
