From 5424a44276ee60d39335ba037c7e142fad4a259a Mon Sep 17 00:00:00 2001 From: RD Babiera Date: Fri, 23 Feb 2024 00:23:03 +0000 Subject: [PATCH] usb: typec: altmodes/displayport: send configure message on sop' When the port is setting the pin configuration when no configuration is chosen, the DisplayPort driver will not send Configure to the cable plug if it's available. Add transition to DP_STATE_CONFIGURE_PRIME.
