[PATCH V5 01/16] drm/amd/pm: do not expose implementation details to other blocks out of power

Evan Quan evan.quan at amd.com
Mon Dec 13 03:52:08 UTC 2021


Those implementation details(whether swsmu supported, some ppt_funcs supported,
accessing internal statistics ...)should be kept internally. It's not a good
practice and even error prone to expose implementation details.
