From 7c68ed04c389691b2f82e7853530096601a55b0c Mon Sep 17 00:00:00 2001 From: Dmitry Baryshkov Date: Thu, 16 Mar 2023 19:16:40 +0300 Subject: [PATCH] drm/msm/dpu: make _dpu_plane_calc_clk accept mode directly Rework bandwidth/clock calculation functions to use mode directly rather than fetching it through the plane data.
