2019-01-17drm/amdgpu: Add APTX quirk for Lenovo laptopAlex Deucher

2019-01-16drm/amd/display: Detach backlight from streamDavid Francis
[Why] Backlight is conceptually a property of links, not streams. All backlight programming is done on links, but there is a stream property bl_pwm_level that is used to restore backlight on dpms on and s3 resume. This is unnecessary, as backlight is already restored by hardware with no driver intervention.

2019-01-14drm/amd/display: Only get the connector state for VRR when toggledNicholas Kazlauskas
[Why] This fixes a stuttering issue that occurs when moving a hardware cursor when VRR is enabled. Previously when VRR is enabled atomic check will grab the connector state for every atomic update. This has to lock the connector in order to do so. The locking is bad enough by itself for performance, but it gets worse with what we do just below that - add all the planes for the CRTC to the commit. This prevents the cursor fast path from working - there's more than one plane now. With state->allow_modeset = true on top of this, it also adds and removes all the planes from the DC context triggering a full (very slow) update in DC. [How] We need the connector state to get the VRR min/max capbilities, but we only need them when there's a CRTC mode change or when VRR is toggled. The condition has been updated accordingly.
