i.MX8MM using DSI to HDMI converter (Audio Sync)

[EErdem]

Hello, I am using a DSI to HDMI bridge to get HDMI output.

My bridge IC is different from EVKs and it has I2S input to provide audio data with video data over HDMI.

Q1: Is there any dedicated I2S pins to ensure Video and Audio Sync

Q2: If it is okey to use any of SAI pins how can I make sure that Video and Audio outputs are delivered within sync.
