[PATCH 2/3] drm/amdgpu: Correct the read sclk for navi10

[Feng, Kenneth]

[AMD Official Use Only - Internal Distribution Only]

Hello Emily,
The average clock value is a little different from the 'current clock' value.
May I know what's the purpose of this patch to display the average clock? Any issue or any customer requirement?
Thanks.


Best Regards
Kenneth

According to hw, after navi10,it runs in dfll mode, and should read sclk from AverageGfxclkFrequency.
