From 9ffbf5ef0e8d6e1b76440a6d77311d0c5d6e3979 Mon Sep 17 00:00:00 2001 From: Abhinav Kumar Date: Mon, 2 Dec 2024 12:41:59 -0800 Subject: [PATCH] drm/msm/dp: do not touch the MMSS_DP_INTF_CONFIG for tpg MMSS_DP_INTF_CONFIG has already been setup by the main datapath for DP to account for widebus to be used/unused etc. In current implementation, TPG only switches the DP controller to use the main datapath stream OR use the test pattern but expects the rest of the controller to be already setup. Keeping the same behavior intact, drop the clearing of MMSS_DP_INTF_CONFIG from the msm_dp_catalog_panel_tpg_enable() API.
