Subject: [PATCH 2/3] usb: chipidea: imx: support disabling runtime-pm
Date: Fri, 10 Jul 2020 17:49:33 +0200	[thread overview]
Message-ID: <20200710154935.697190-2-philippe.schenker@toradex.com> (raw)
In-Reply-To: <20200710154935.697190-1-philippe.schenker@toradex.com>

Chipidea depends on some hardware signals to be there in order
for runtime-pm to work well. Add the possibility to disable runtime
power management that is necessary for certain boards.
