drm/amd/display: Fix type of pp_smu_wm_set_range struct

2019-05-31T15:39:32+00:00

[why]
Value read from SMU is 16 bits, not 32.

[How]
Fix type, and add wm_type enum in preparation for future interfaces.

drm/amd/display: Set dispclk and dprefclock directly

2019-05-24T17:20:49+00:00

[Why]
To simply logic for setting DCN specific clocks, we will send
SMU message directly through the VBIOS message box.

[How]
Add new structure in pp_smu to hold functions to set clocks
through vbios message box

drm/amd/display: PPLIB Hookup

2019-03-05T20:09:32+00:00

[Why]
Make dml and integration with pplib clearer.

[How]
Change the way the dml formula is initialized to make its values more
clear. Restructure DC interface with pplib into rv_funcs.
Cap clocks received from pplib.

drm/amd/display: Clean up for DCN1 clock debug logging

2018-11-30T17:04:45+00:00

[Why]
To prepare for clock debug logging. With the exception of removing
max_supported_dppclk_khz from logs, there are no functional changes.

[How]
Add clk_bypass struct and clean up buffer logic

drm/amd/display: Retiring set_display_requirements in dm_pp_smu.h - part4

2018-11-05T19:21:41+00:00

[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.

drm/amd/display: Retiring set_display_requirements in dm_pp_smu.h - part3

2018-11-05T19:21:11+00:00

[Why]
In DCN we want direct DAL to SMU calls, with as little as
possible interference by 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 dal and shared across different OS. This will also
simplify debugging as DAL owns this interaction and there's no
confusion about division of ownership.

[How]
Separate the set_hard_min_fclk_by_freq message from the
SMU messages that are sent as part of pp_rv_set_display_requirement.
directly notify min dcfclk to smu part 2
