Subject: [PATCH 1/3] dt-bindings: usb: ci-hdrc-usb2: add property disable-runtime-pm
Date: Fri, 10 Jul 2020 17:49:32 +0200 [thread overview]
Message-ID: <20200710154935.697190-1-philippe.schenker@toradex.com> (raw)
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.
