Subject: [RESEND PATCH v2 1/2] ARM: dts: colibri-imx6: add usb dual-role switch capability
Date: Thu, 16 Jul 2020 14:58:29 +0200	[thread overview]
Message-ID: <20200716125831.796904-2-philippe.schenker@toradex.com> (raw)
In-Reply-To: <20200716125831.796904-1-philippe.schenker@toradex.com>

Since the runtime-pm wakeup bug was fixed in
drivers/usb/chipidea/core.c usb dual-role host/device switching is
working. So make use of it.
