From 4aebe73f44bb57ccc8bcdba15a2d56ebfe452d4d Mon Sep 17 00:00:00 2001 From: Roman Li Date: Mon, 13 Apr 2026 17:32:34 -0400 Subject: [PATCH] drm/amd/display: Add allow_clock_gating to dcn42 dccg [Why] The allow_clock_gating function is present in all other DCN versions and is required to properly migrate DCCG registers access from hwseq to the dccg component, resolving register conflicts. [How] Add the missing .allow_clock_gating function pointer to the dccg42_funcs struct.
