2025-01-10drm/amd/display: DML2.1 Post-Si CleanupRafal Ostrowski1-114/+15
[Why] There are a few cleanup and refactoring tasks that need to be done with the DML2.1 wrapper and DC interface to remove dependencies on legacy structures and N-1 prototypes. [How] Implemented pipe_ctx->global_sync. Implemented new functions to use pipe_ctx->hubp_regs and pipe_ctx->global_sync: - hubp_setup2 - hubp_setup_interdependent2 - Several other new functions for DCN 4.01 to support newer structures Removed dml21_update_pipe_ctx_dchub_regs Removed dml21_extract_legacy_watermark_set Removed dml21_populate_pipe_ctx_dlg_param Removed outdated dcn references in DML2.1 wrapper.

Use more accurate names to refer to the asic architecture. dcn3 in DML actually refers to DCN32 and DCN321, so rename it to dcn32x dcn4 refers to any DCN4x soc., and hence rename dcn4 to dcn4x Reviewed-by: Rodrigo Siqueira <rodrigo.siqueira@amd.com> Signed-off-by: Aurabindo Pillai <aurabindo.pillai@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
