From 350753bf2bd1267f471e89829d68c35b9abf4930 Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Tue, 21 May 2013 12:39:31 +0200 Subject: [PATCH 1/2] sh-pfc: r8a7779: Don't group USB OVC and PENC pins The USB_OVCn pins are alternate options for USB over-current detection when using a 3.3V USB interface. As they're not mandatory they can be used independently of the USB PENC pins. Don't group the USB_OVCn and PENC pins to avoid conflicts when the USB_OVCn pins are used by another function.

This resolves a boot-failure regression for kzm9g-reference in v3.10-rc1 introduced by f7db706b132f11c79ae1d74b2382e0926cf31644 ("ARM: 7674/1: smp: Avoid dummy clockevent being preferred over real"). The patch noted above reduces the rating of dummy clockevent from 400 to 100. This patch reduces the rating of CMT so that it is once again less than that of the dummy clockevent.
