drm/amd/display/dc/bios_parser2: Mark expected switch fall-throughs

2019-02-18T23:01:00Z

In preparation to enabling -Wimplicit-fallthrough, mark switch cases where we are expecting to fall through. Warning level 3 was used: -Wimplicit-fallthrough=3 This patch is part of the ongoing efforts to enable -Wimplicit-fallthrough. Signed-off-by: Gustavo A. R. Silva Signed-off-by: Alex Deucher

drm/amd/display: Connect dig_fe to otg directly instead of calling bios

2019-01-25T21:15:37Z

[Why] After call bios table crtc_source_select, dal will program fmt again. The bios table program dig_source_select and other fmt register for bios usage which is redundancy and uncessary. [How] Program dig_soruce_select register directly Signed-off-by: hersen wu Reviewed-by: Charlene Liu Acked-by: Leo Li Signed-off-by: Alex Deucher

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

2019-01-25T21:15:37Z

[Why] This change causes regression for S4 resume where gamma is not programmed. The change incorrectly updates the requested dpms_off state.

drm/amd/display: fix eDP fast bootup for pre-raven asic

2019-01-25T21:15:36Z

[Why] For fastboot, Bios will light up eDP before SW driver is loaded. SW driver will check if eDP is lit by bios through reading the BIOS_SCRATCH_3 register. If lit, SW driver will not power down eDP power and phy to save time. Definition of BIOS_SCRATCH_3 are missing for pre-raven asic. This causes eDP fast boot to not work property. For some eDP panels, even if dp tx sends NoVideoStream_flag =1 and dpcd 0x600=2, eDP rx may not handle properly. This may cause a short flash on screen.

drm/amd/display: Use 100 Hz precision for pipe pixel clocks

2019-01-14T20:04:39Z

[Why] Users would like more accurate pixel clocks, especially for fractional "TV" frame rates like 59.94 Hz. [How] Store and communicate pixel clocks with 100 Hz accuracy from dc_crtc_timing through to BIOS command table setpixelclock call.

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.
