drm/dp: Bit definition for D3 power state that keeps AUX fully powered
DPCD 600h - SET_POWER & SET_DP_PWR_VOLTAGE defines power state 101 = Set Main-Link for local Sink device and all downstream Sink devices to D3 (power-down mode), keep AUX block fully powered, ready to reply within a Response Timeout period of 300us. This state is useful in a MST dock + MST monitor configuration that doesn't wake up from D3 state. v2: Use spaces instead of tabs (Jani) Reviewed-by: Harry Wentland <harry.wentland@amd.com> Signed-off-by: Dhinakaran Pandiyan <dhinakaran.pandiyan@intel.com> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/1502475008-2035-1-git-send-email-dhinakaran.pandiyan@intel.com
