From: Archit Taneja Date: Thu, 23 Mar 2017 10:28:09 +0000 (+0530) Subject: drm/msm/mdp5: Create mdp5_hwpipe_mode_set X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=821be43ff2424b13bc6152360eb6d5bacfbf8530;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git drm/msm/mdp5: Create mdp5_hwpipe_mode_set Refactor mdp5_plane_mode_set to call mdp5_hwpipe_mode_set. The latter func takes in only the hwpipe and the parameters that need to be programmed into the hwpipe registers. All the code that calculates these parameters is left as is in mdp5_plane_mode_set. In the future, when we let drm_plane be comprised of 2 hwpipes, this func allow us to configure each pipe without adding redundant code.
