From 78d2b54b134ea6059e2b1554ad53fab2300a4cc6 Mon Sep 17 00:00:00 2001 From: Heikki Krogerus Date: Thu, 20 Sep 2018 14:23:42 +0300 Subject: [PATCH] platform: x86: intel_cht_int33fe: Add connection for the DP alt mode Adding a connection for the DisplayPort alternate mode. PI3USB30532 is used for muxing the port to DisplayPort on CHT platforms. The connection allows the alternate mode device to get handle to the mux, and therefore make it possible to use the USB Type-C connector as DisplayPort.
