[PATCH V5 00/16] Unified entry point for other blocks to interact with power

There are several problems with current power implementations:
1. Too many internal details are exposed to other blocks. Thus to interact with
power, they need to know which power framework is used(powerplay vs swsmu)
or even whether some API is implemented.
2. A lot of cross callings exist which make it hard to get a whole picture of
the code hierarchy. And that makes any code change/increment error-prone.
3. Many different types of lock are used. It is calculated there is totally
13 different locks are used within power. Some of them are even designed for
the same purpose.
To ease the problems above, this patch series try to
1. provide unified entry point for other blocks to interact with power.
2. relocate some source code piece/headers to avoid cross callings.
3. enforce a unified lock protection on those entry point APIs above.
That makes the future optimization for unnecessary power locks possible.
Evan Quan (16):
drm/amd/pm: do not expose implementation details to other blocks out
of power
drm/amd/pm: do not expose power implementation details to amdgpu_pm.c
drm/amd/pm: do not expose power implementation details to display
drm/amd/pm: do not expose those APIs used internally only in
amdgpu_dpm.c
drm/amd/pm: do not expose those APIs used internally only in si_dpm.c
drm/amd/pm: do not expose the API used internally only in kv_dpm.c
drm/amd/pm: create a new holder for those APIs used only by legacy
ASICs(si/kv)
drm/amd/pm: move pp_force_state_enabled member to amdgpu_pm structure
drm/amd/pm: optimize the amdgpu_pm_compute_clocks() implementations
drm/amd/pm: move those code piece used by Stoney only to smu8_hwmgr.c
drm/amd/pm: drop redundant or unused APIs and data structures
drm/amd/pm: do not expose the smu_context structure used internally in
power
drm/amd/pm: relocate the power related headers
drm/amd/pm: drop unnecessary gfxoff controls
drm/amd/pm: revise the performance level setting APIs
drm/amd/pm: unified lock protections in amdgpu_dpm.c
