Subject: [PATCH 0/6] usb: Linking ports to their Type-C connectors
Date: Thu, 25 Mar 2021 15:29:20 +0300	[thread overview]
Message-ID: <20210325122926.58392-1-heikki.krogerus@linux.intel.com> (raw)

Hi,

Adding a simple function typec_link_port() that can be used to create
a symlink "connector" that points to the USB Type-C connector of a
port. It is used with USB ports initially, but hopefully later also
with other things like DisplayPorts.

Being able to see which connector is connected to a port is important
in general, but it is really important when for example the data or
power role of a device needs to swapped. The user probable wants to
know which USB device is disconnected if role swap on a USB Type-C
connector is executed.

Hope these are OK.

thanks,
