[PATCH V2 07/17] drm/amd/pm: create a new holder for those APIs used only by legacy ASICs(si/kv)
Evan Quan

Tue Nov 30 07:42:49 UTC 2021
Those APIs are used only by legacy ASICs(si/kv). They cannot be
shared by other ASICs. So, we create a new holder for them.

v1->v2:
- move other APIs used by si/kv in amdgpu_atombios.c to the new
holder also(Alex)
