2019-08-23drm/amdgpu/display: add flag for multi-display mclk switchingAlex Deucher
Add a dcfeaturemask flag for mclk switching. Disable by default; enable once the feature has seen more testing. Set amdgpu.dcfeaturemask=2 on the kernel command line in grub to enable this.

2019-07-18drm/amd/display: add dcc programming for dual planeDmytro Laktyushkin
Add dual plane dcc programming support for surfaces. Removes unions from plane size and dcc params as they serve no practical purpose only making our code more convoluted. This results in easy dual plane dcc and surface size programming. Temporary diags_dm code is used to handle the interface change without breaking functionality as a diags change needs to be applied after this one.
