[Why] There are currently two interfaces for exactly the same thing: hupb_update_dchub in hupb and update_dchub in hubbub. The hubbub version is currently unused past dcn10, largely because the call from the dcn10 hardware sequencer does not call through the interface, so the hupb interface was used instead.

[why] At the time DIG FE is connected to its BE, the clocks in OTG are enabled and PHY will also be set up. When DSC has to be used to fit the stream into the available bandwidth, without DSC being set DIG could get exposed to the higer bandwidth it (or link) could handle. This causes the HW to "reject" video enable setup (the register shows that video enable was attempted, but the status bit shows it as disabled). [how] - Separate DSC setup into DSC register config and DSC PPS SDP setup - Move most of the DSC setup (register config) to before dcn10_link_encoder_connect_dig_be_to_fe() is called - Set up DSC PPS SDP after DIG FE is connected to its BE.

2019-08-15drm/amd/display: fixup DPP programming sequenceJun Lei3-4/+10
[why] DC does not correct account for the fact that DPP DTO is double buffered while DPP ref is not. This means that when DPP ref clock is lowered when it's "safe to lower", the DPP blocks that need an increased divider will temporarily have actual DPP clock drop below minimum while DTO double buffering takes effect. This results in temporary underflow. [how] To fix this, DPP clock cannot be programmed atomically, but rather be broken up into the DTO and the ref. Each has a separate "safe to lower" logic. When doing "prepare" the ref and dividers may only increase. When doing "optimize", both may decrease. It is guaranteed that we won't exceed max DPP clock because we do not use dividers larger than 1.

2019-08-15drm/amd/display: Synchronous DisplayPort Link TrainingDavid Galiffi2-2/+3
[WHY] We require a method to perform synchronous link training. [HOW] Sync LT is broken into 3 basic steps. "Begin" starts the state machine, and resets "preferred" link settings. "Attempt" will attempt to train the link with a given set of training parameters. "End" stops the state machine, and will optionally disable the link phy. Between "Begin" and "End" DPCD:600h must not be set to "2" (D3:Powered Down). Between "Begin" and "End", there may be multiple "Attempts" with different training parameters.
