2019-10-10drm/amd/display: Fix dongle_caps containing stale information.David Galiffi
[WHY] During detection: function: get_active_converter_info populates link->dpcd_caps.dongle_caps only when dpcd_rev >= DPCD_REV_11 and DWN_STRM_PORTX_TYPE is DOWN_STREAM_DETAILED_HDMI or DOWN_STREAM_DETAILED_DP_PLUS_PLUS. Otherwise, it is not cleared, and stale information remains.

[why] During detection link training if a display is disconnected, the current code will retry 3 times of link training on disconnected link before giving up. [how] Before each retry check for HPD status, only retry verify link cap when HPD is still high. Also put a 10ms delay between each retry to improve the chance of success.

[Why] The vm config will be clear to 0 when system enter S4. It will cause hubbub didn't know how to fetch data when system resume.

[Why and How] We want to change where timing is done for alt mode. Some of the commented out #ifs are needed for DCN20 so we enable them for that case.

2019-08-15drm/amd/display: Set DSC before DIG front-end is connected to its back-endNikola Cornij
[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. This is because setting DSC PPS SDP before that has no effect.
