From c698316661096e036b54448039b35e1c2c5809f0 Mon Sep 17 00:00:00 2001 From: Benson Leung Date: Mon, 17 Jul 2017 11:41:39 +0200 Subject: extcon: cros-ec: Add extcon-cros-ec driver to support display out This is the driver for the USB Type C cable detection mechanism built into the ChromeOS Embedded Controller on systems that have USB Type-C ports. At present, this allows for the presence of display out, but in future, it may also be used to notify host and device type cables and the presence of power.
