Subject: [PATCH v3 0/9] device connection: Add support for device graphs

Hi,

This is the third version of my proposal to add device graph parsing
to the device connection API. There was only one problem reported in
v2 by Jun - kernel-doc entry was missing for the new fwnode member in
struct usb_role_switch_desc - and it's now fixed.

The second version of the series:
https://lkml.org/lkml/2019/1/30/622

The commit message from v1:

This series adds support for OF and ACPI device graph parsing to the
device connection API.

Handling the graph is straightforward, but because I'm adding that
fwnode member to struct device_connection, I had to make sure all the
existing users consider it.

The plan is to only support matching with fwnode in the future, so no
more device name matching. The software fwnodes that we now have in
kernel should make that possible, once we add support for references
to them.

The original RFC:

thanks,
