From 588715bdcfbc2592f50b433a3ebaac72014d5fb4 Mon Sep 17 00:00:00 2001 From: hersen wu Date: Wed, 28 Nov 2018 16:57:56 -0500 Subject: [PATCH] drm/amd/display: dal-pplib interface refactor dal part [WHY] clarify dal input parameters to pplib interface, remove un-used parameters. dal knows exactly which parameters needed and their effects at pplib and smu sides. current dal sequence for dcn1_update_clock to pplib: 1.smu10_display_clock_voltage_request for dcefclk 2.smu10_display_clock_voltage_request for fclk 3.phm_store_dal_configuration_data { set_min_deep_sleep_dcfclk set_active_display_count store_cc6_data --- this data never be referenced new sequence will be: 1. set_display_count --- need add new pplib interface 2. set_min_deep_sleep_dcfclk -- new pplib interface 3. set_hard_min_dcfclk_by_freq 4. set_hard_min_fclk_by_freq after this code refactor, smu10_display_clock_voltage_request, phm_store_dal_configuration_data will not be needed for rv.
