Subject: [PATCH 0/2] Two cpp41 pm runtime found when testing with usb
Date: Wed, 9 Nov 2016 09:47:57 -0700 [thread overview]
Message-ID: <20161109164759.24913-1-tony@atomide.com> (raw)
Hi,
I found two pm runtime issues when testing with usb on beaglebone.
In the am335x case cppi41 and two instances of musb controller share
the same interconnect wrapper module, so any pm issues with musb or
cppi41 will keep the interconnect wrapper module busy.
Regards,
Tony
