SN75DP139: About I2C

Part Number: SN75DP139

HI,

I used Intel tiger lake platform, tiger lake DDI both support DP and HDMI, but SN75DP139 support DP to TMDS.

I need connect AUX pin to SN75DP139 transfer to HDMI I2C? Or I can connect tiger lake HDMI I2C to HDMI port directly and do not pass though  SN75DP139?

Thanks!

Jeff
