Subject: [PATCH v4 2/5] usb: musb: Use shared irq
Date: Tue, 24 Jan 2017 11:11:46 +0100 [thread overview]
Message-ID: <20170124101149.14920-3-abailon@baylibre.com> (raw)
In-Reply-To: <20170124101149.14920-1-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.
