Subject: [PATCH v3 2/5] usb: musb: Use shared irq
Date: Thu, 19 Jan 2017 15:08:32 +0100	[thread overview]
Message-ID: <20170119140835.18981-3-abailon@baylibre.com> (raw)
In-Reply-To: <20170119140835.18981-1-abailon-rdvid1DuHRBWk0Htik3J/w@public.gmane.org>

In the DA8xx, USB and CPPI 4.1 are sharing the same interrupt line.
Update the driver to request a shared irq.
