From 6e62223f01bedd20628845f2c2dd0371715aa4aa Mon Sep 17 00:00:00 2001 From: Caveh Jalali Date: Tue, 30 Jun 2020 03:13:07 -0700 Subject: mb/google/volteer: Add support for passive USB-C daughterboard The USB-C SBU and HSL orientation configuration depends on the USB daughterboard used on the system. This patch adds an additional configuration for supporting passive USB daughterboards using "probe" directives to select the appropriate configuration at runtime.
