[PATCH] drm/msm/mdp: Add capabilities to MDP planes
From: Jilai Wang
Date: Tue Jul 07 2015 - 17:17:23 EST
MDP planes can be implemented using different type of HW pipes,
RGB/VIG/DMA pipes for MDP5 and RGB/VG/DMA pipes for MDP4. Each type
of pipe has different HW capabilities such as scaling, color space
conversion, decimation... Add a variable in plane data structure
to specify the difference of each plane which comes from mdp5_cfg data
and use it to differenciate the plane operation.
