Subject: [PATCH 0/4] usb: musb: support for suspend and resume
Date: Thu, 26 Sep 2013 15:08:58 +0200 [thread overview]
Message-ID: <1380200942-28175-1-git-send-email-zonque@gmail.com> (raw)
I've been working on some patches that allow suspending and resuming
the musb-dsps platform. This was tested for host mode only.
With these patches applied, I can successfully bring an AM335x board
to suspend with a USB media connected, and access it again after
resume. Note that this currently only works with CONFIG_MUSB_PIO_ONLY
set. The cppi41 driver needs some more love to make this work. I'll
work on that next.
Thanks,
Daniel
