How to check for CSI lane on the MIPI driver source with debug message.

Hi All,

I wonder that how to check for CSI lane on the MIPI driver source with debug message.

For example, I want to know csi lane number connected with TX0 and TX1 port in the tc358840.c of hdmitocsi driver.

I saw the tc358840_log_status() function. but, I can’t check log message this status log.

Could you let me know your idea?

Thanks & BR,
