Subject: [PATCH 3/4] usb: musb: Use shared irq
Date: Mon, 9 Jan 2017 17:39:01 +0100 [thread overview]
Message-ID: <20170109163902.5268-4-abailon@baylibre.com> (raw)
In-Reply-To: <20170109163902.5268-1-abailon-rdvid1DuHRBWk0Htik3J/w@public.gmane.org>
In the da8xx, usb core and cppi41 are sharing the same interrupt line.
Update the driver to request a shared irq.
