kernel/drivers/gpu/drm/amd/display/dc/dce100, branch linux-5.1.y

Merge v5.0 into drm-next

2019-03-04T02:02:55Z

There is a really hairy resolution involving amdgpu fixes, that I'd rather confirm here. Also some misc fixes are landed by me, but the pr has them as well. Signed-off-by: Dave Airlie

drm/amd/display: fix optimize_bandwidth func pointer for dce80

2019-02-20T21:57:47Z

[Why] optimize_bandwidth was using dce100_prepare_bandwidth this is incorrect [How] change it to dce100_optimize_bandwidth Signed-off-by: Bhawanpreet Lakha Reviewed-by: Charlene Liu Acked-by: Leo Li Signed-off-by: Alex Deucher Cc: stable@vger.kernel.org

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.

drm/amd/display: Allow clock lower on dce100

2018-11-30T17:03:37Z

dce100 was set to always pass safe_to_lower = false to the clock manager Thus, on suspend the clocks were not being set to 0 which is incorrect behaviour This was causing s3 resume to blackscreen on intel CPUs with dce100 GPUs attached (Note that the hash in this Fixes: tag is the hash on Alex's tree) Fixes: ae7d8aeb38d7 ("drm/amd/display: remove safe_to_lower flag from dc, use 2 functions instead") Signed-off-by: David Francis Reviewed-by: Harry Wentland Acked-by: Leo Li Signed-off-by: Alex Deucher

drm/amd/display: rename dccg to clk_mgr

2018-11-05T19:20:48Z

In preparation for adding the actual dccg block since the current implementation of dccg is mor eof a clock manager than a hw block Signed-off-by: Dmytro Laktyushkin Reviewed-by: Charlene Liu Acked-by: Bhawanpreet Lakha Signed-off-by: Alex Deucher

drm/amd/display: split dccg clock manager into asic folders

2018-11-05T19:20:42Z

Currently dccg contains code related to every dcn revision in a single file. This change splits out the dcn parts of code into correct folders Signed-off-by: Dmytro Laktyushkin Reviewed-by: Charlene Liu Acked-by: Bhawanpreet Lakha Signed-off-by: Alex Deucher

drm/amd/display: remove safe_to_lower flag from dc, use 2 functions instead

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.
