From: Archit Taneja Date: Thu, 23 Mar 2017 10:27:55 +0000 (+0530) Subject: drm/msm/mdp5: describe LM instances in mdp5_cfg X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=384dbd8cda5f9e1090b3593fd63ca3c84b2fdd1b;p=openwrt%2Fstaging%2Fblogic.git drm/msm/mdp5: describe LM instances in mdp5_cfg The number of Layer Mixers and the downstream blocks (DSPPs and PPs) connected to each LM can vary with different MDP5 revisions. These parameters are also static. Keep the per instance LM data in mdp5_cfg. This will avoid the need to have macros which identify PP id or DSPP id the LM is connected to. We don't configure DSPPs at the moment, but keeping the DSPP instance # here might come handy later. Also add a 'caps' field that identifies features supported by a LM instance. Introduce the caps MDP_LM_CAP_DISPLAY and MDP_LM_CAP_WB that identify whether a LM instance can be used for display or writeback.
