Subject: [PATCH 0/8] USB ehci/chipidea fixes
Date: Fri, 26 Oct 2018 11:33:30 +0200 [thread overview]
Message-ID: <20181026093338.22751-1-s.hauer@pengutronix.de> (raw)
This series fixes messages seen on i.MX when multiple chipidea
instances are registered:
ERROR: imx-usb 53f80000.usb: gadget not registered.
While I originally thought this is a simple one it turned out there
are several things wrong in the ehci/chipidea (un)registration code.
Most notably the ehci controllers were often not properly quiesced when
leaving barebox.
