2020-08-26drm/amd/display: Reject overlay plane configurations in multi-display scenariosNicholas Kazlauskas
[Why] These aren't stable on some platform configurations when driving multiple displays, especially on higher resolution. In particular the delay in asserting p-state and validating from x86 outweights any power or performance benefit from the hardware composition. Under some configurations this will manifest itself as extreme stutter or unresponsiveness especially when combined with cursor movement. [How] Disable these for now. Exposing overlays to userspace doesn't guarantee that they'll be able to use them in any and all configurations and it's part of the DRM contract to have userspace gracefully handle validation failures when they occur. Valdiation occurs as part of DC and this in particular affects RV, so disable this in dcn10_global_validation.

2020-08-26drm/amd/display: use correct scale for actual_brightnessAlexander Monakov
Documentation for sysfs backlight level interface requires that values in both 'brightness' and 'actual_brightness' files are interpreted to be in range from 0 to the value given in the 'max_brightness' file. With amdgpu, max_brightness gives 255, and values written by the user into 'brightness' are internally rescaled to a wider range. However, reading from 'actual_brightness' gives the raw register value without inverse rescaling. This causes issues for various userspace tools such as PowerTop and systemd that expect the value to be in the correct range. Introduce a helper to retrieve internal backlight range. Use it to reimplement 'convert_brightness' as 'convert_brightness_from_user' and introduce 'convert_brightness_to_user'.

2020-08-26drm/bridge_connector: Set default status connected for eDP connectorsEnric Balletbo i Serra
In an eDP application, HPD is not required and on most bridge chips useless.

2020-08-26loop: Set correct device size when using LOOP_CONFIGUREMartijn Coenen
The device size calculation was done before processing the loop configuration, which meant that the we set the size on the underlying block device incorrectly in case lo_offset/lo_sizelimit were set in the configuration. Delay computing the size until we've setup the device parameters correctly.
