Hi,

My system ls1021a has TYPE C connector and CC controller PTN5150 and a MUX, I would like to know how to add this module (PTN5150) into my Linux so that I can configure the settings of this chip through I2C from Linux.

Linux kernel 4.19

Debian

LSDK1906

Do I need to add anything into the Makefile as well for the object file of this driver compilation ?
