Hi,

This removes the need for the drivers to always separately evaluate
the _PLD. With the USB Type-C connector and USB port mapping this
allows us to start using the component framework and remove the custom
APIs.

So far the only users of the _PLD information have been the USB
drivers, but it seems it will be used also at least in some camera
drivers later. These nevertheless touch mostly USB drivers.

Rafael, is it still OK if Greg takes these?

Prashant, can you test these?

thanks,

Heikki Krogerus (5):

  usb: Use the cached ACPI _PLD entry
  usb: Link the ports to the connectors they are attached to
  usb: typec: port-mapper: Convert to the component framework
  usb: Remove usb_for_each_port()
