+Subject: [PATCH] USB: bcma: initialize Northstar USB 3.0 controller
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+It's a rather simple controller, we just need to make sure USB is
+powered (using GPIO pin) and reset bus core. Once this is done it's
+safe to register XHCI controller and let it init PHY and do its magic.
