drm/amd/display: Add functionality to get XGMI SS info

2018-12-18T22:39:56Z

[Why] When XGMI is enabled, the DP reference clock needs to be adjusted according to the XGMI spread spectrum percentage and mode. But first, we need the ability to fetch this info. [How] Within the BIOS parser, Read from vBIOS when XGMI SS info is requested. In addition, diags build uses include_legacy/atomfirmware.h for the smu_info_v3_3 table headers. Update that as well.

drm/amd/display: Add DCE_VERSION_12_1 enum for Vega 20

2018-12-18T22:39:49Z

[Why] We'll need a way to differentiate Vega 20 in DC [How] Add a DCE_VERSION_12_1 enum, which will be returned as the DC version if the ASIC used is a Vega 20. Signed-off-by: Leo Li Reviewed-by: David Francis Signed-off-by: Alex Deucher

drm/amd/display: Add condition to sync eDP SW status and HW status

2018-11-05T19:21:45Z

[Why] Need to disable EDP backlight when enter S4 with EDP only and resume from S4 with secondary only. [How] Align the real hw and sw state via vBios scratch register in function enable_accelerated_mode when resume from S4.

drm/amd/display: Create new i2c resource

2018-08-27T16:11:05Z

[Why] I2C code did not match dc resource model and was generally unpleasant [How] Move code into new svelte dce_i2c files, replacing various i2c objects with two structs: dce_i2c_sw and dce_i2c_hw. Fully split sw and hw code paths. Remove all redundant declarations. Use address lists to distinguish between versions. Change dce80 code to newer register access macros.

drm/amd/display: Set DFS bypass flags for dce110

2018-08-27T16:09:49Z

[Why] While there is support for using and quering DFS bypass clocks the hardware is never notified to enter DFS bypass mode for dce110. [How] Add a flag that can be set when programming the display engine PLL to enable DFS bypass mode. If this flag is set then the hardware is notified to enter DFS bypass mode and the correct display engine clock frequency can be acquired.

drm/amd/display: update clk for various HDMI color depths

2018-08-06T20:57:29Z

[why] When programming tonga's connector's backend we didn't take in account that HDMI's colour depth might be more than 8bpc therefore we need to add a switch statement that would adjust the pixel clock accordingly. [how] Add a switch statement updating clock by its appropriate coefficient.
