[PATCH 4/4] drm/amd/pp: Implement set_power_profile_mode on smu7

[Zhu, Rex]

Hi Eric,

We have sysfs pp-dpm-sclk/mclk to set min dpm level

Best Regards
Rex

Subject: Re: [PATCH 4/4] drm/amd/pp: Implement set_power_profile_mode on smu7

We have min_sclk and min_mclk in previous power profile parameters for
VI, which are similar with min_active_level for Vega10. How to implement
these parameters?

Regards,
Eric
