From 9338aacf01466d6f43c73b2182d5a42228fe63d7 Mon Sep 17 00:00:00 2001 From: Heikki Krogerus Date: Fri, 31 May 2019 17:15:45 +0300 Subject: platform/x86: intel_cht_int33fe: Provide fwnode for the USB connector In ACPI, and now also in DT, the USB connectors usually have their own device nodes. In case of USB Type-C, those connector (port) nodes are child nodes of the controller or PHY device, in our case the fusb302. The software fwnodes allow us to create a similar child node for fusb302 that represents the connector also on Intel CHT. This makes it possible replace the fusb302 specific device properties which were deprecated with the common USB connector properties that tcpm.c is able to use directly.
