Hi,

Could someone clarify how to check HDMI TMDS clock frequency and DisplayPort link symbol clock frequency?

- Is there some registers which can dump the clock frequency?

- Is 'clock' field in 'struct drm_display_mode' reflect the this clock?

My platform is Haswell, Broadwell and Baytrail (Valleyview).

I want to check

- TMDS clock frequency for HDMI

- Link Symbol clock for DP

One test monitor has problem to play 48khz audio. So I want to make sure N/M/CTS values are right for the display clock and audio sample rate.

Thanks Mengdong
