2019-05-31drm/amd/display: Fix type of pp_smu_wm_set_range structEric Yang
[why] Value read from SMU is 16 bits, not 32. [How] Fix type, and add wm_type enum in preparation for future interfaces.

2018-11-05drm/amd/display: Retiring set_display_requirements in dm_pp_smu.h - part4Fatemeh Darbehani
[Why] In DCN we want direct DC to SMU calls, with minimal interference from pplib. The reason for each pp_smu interface mapping to 1 SMU message is so we can have the sequencing of different SMU message in DC and shared across different OS's. This will also simplify debugging as DAL owns this interaction and there's no confusion about division of ownership. [How] Part 4: Change clock units so they match the values PPLib sends to SMU.
