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: Change from aux_engine to dce_aux

2019-01-14T20:40:48Z

[Why] The aux_engine struct is needlessly complex and is defined multiple times. It contains function pointers that each have only one version and are called only from inside dce_aux. [How] Replace aux_engine with a new struct called dce_aux. Remove all function pointers and call functions directly. Remove unused functions Signed-off-by: David Francis Reviewed-by: Harry Wentland Acked-by: Leo Li Signed-off-by: Alex Deucher

drm/amd/display: remove sink reference in dc_stream_state

2019-01-14T20:04:36Z

[why] dc_stream_state containing a pointer to sink is poor design. Sink describes the display, and the specifications or capabilities it has. That information is irrelevant for dc_stream_state, which describes hardware state, and is generally used for hardware programming. It could further be argued that dc_sink itself is just a convenience dc provides, and DC should be perfectly capable of programming hardware without any dc_sinks (for example, emulated sinks). [how] Phase 1: Deprecate use of dc_sink pointer in dc_stream. Most references are trivial to remove, but some call sites are risky (such as is_timing_changed) with no obvious logical replacement. These will be removed in follow up change. Add dc_link pointer to dc_stream. This is the typical reason DC really needed sink pointer, and most call sites are replaced with this. DMs also need minor updates, as all 3 DMs leverage stream->sink for some functionality. this is replaced instead by a pointer to private data inside dc_stream_state, which is used by DMs as a quality of life improvment for some key functionality. it allows DMs to set pointers have to their own objects which associate OS objects to dc_stream_states (such as DisplayTarget and amdgpu_dm_connector). Without the private pointer, DMs would be forced to perform a lookup for callbacks. Signed-off-by: Jun Lei Reviewed-by: Aric Cyr Acked-by: David Francis Acked-by: Leo Li Signed-off-by: Alex Deucher

drm/amd/display: move pplib/smu notification to dccg block

2018-11-05T19:20:40Z

This is done to clear up the clock programming sequence since the only time we need to notify pplib is after clock update. This also renames the clk block to dccg, at the moment this block contains both clock management and dccg functionality.
