> Subject: [PATCH 2/2] drm/amdgpu: Change pp clock requests to mHz
>
> We were multiplying clock requests by 1000 in amdgpu_dm and then dividing
> them by 1000 in powerplay.
>
> Also, the vega12 code was dividing by 10 when it should have been
> multiplying (to convert units of 10kHz to units of kHz).
