1.Using the FCLK DPM table to set the MCLK for DPM states consist of three entities: FCLK UCLK MEMCLK All these three clk change together, MEMCLK from FCLK, so use the fclk frequency. 2.we should show the current working clock freqency from clock table metric Signed-off-by: Yuxian Dai <Yuxian.Dai@amd.com> Reviewed-by: Alex Deucher <alexander.deucher@amd.com> Reviewed-by: Huang Rui <ray.huang@amd.com> Reviewed-by: Kevin Wang <Kevin1.Wang@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Cc: stable@vger.kernel.org
