--------------------------------- # Enable eDP Hotplug with 6ms pulse register "gpu_dp_d_hotplug" = "0x06"
# Enable DDI1 Hotplug with 6ms pulse register "gpu_dp_b_hotplug" = "0x06"
# Enable DDI2 Hotplug with 6ms pulse register "gpu_dp_c_hotplug" = "0x06"
# Set backlight PWM values for eDP register "gpu_cpu_backlight" = "0x00000200" register "gpu_pch_backlight" = "0x04000200"
# Enable Panel and configure power delays register "gpu_panel_port_select" = "1" # eDP register "gpu_panel_power_cycle_delay" = "6" # 500ms register "gpu_panel_power_up_delay" = "2000" # 200ms register "gpu_panel_power_down_delay" = "500" # 50ms register "gpu_panel_power_backlight_on_delay" = "2000" # 200ms register "gpu_panel_power_backlight_off_delay" = "2000" # 200ms --------------------------------------- I assume SOC has 3 display port, called eDP, DDI1 and DDI2. The code above enable eDP only. How are the DDI1 and DDI2 enabled?
