From c26b4f6cfb2774d13f9ae41cbaaf30f30ac417c6 Mon Sep 17 00:00:00 2001 From: Archit Taneja Date: Thu, 23 Mar 2017 15:58:11 +0530 Subject: drm/msm/mdp5: Configure 'right' hwpipe Now that we have a right hwpipe in mdp5_plane_state, configure it mdp5_plane_mode_set(). The only parameters that vary between the left and right hwpipes are the src_w, src_img_w, src_x and crtc_x as we just even chop the fb into left and right halves. Add a mdp5_plane_right_pipe() which will be used by the crtc code to set up LM stages.
