Subject: drm/amdgpu: add powerplay support for CI asics
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=780cffc599b640f1ea1ab051496ad1fed4532150;p=openwrt%2Fstaging%2Fblogic.git

drm/amdgpu: add powerplay support for CI asics

currently, for CI asics,
use dpm by default, amdgpu.dpm=-1.
when set amdgpu.dpm=1, enable powplay.
when set amdgpu.dpm=0, disable both dpm and powerplay.

when powerplay is stable on CI asics, ci_dpm will
be removed.
