This avoids conflicts when the USB_OVCn pins are used by another function. This has been observed to be a problem in v3.10-rc1. - Update CMT clock rating for sh73a0 SoC to resolve boot failure on kzm9g-reference. This resolves a regression between v3.9 and v3.10-rc1. * tag 'renesas-fixes-for-v3.10' of git://git.kernel.org/pub/scm/linux/kernel/git/horms/renesas: ARM: shmobile: sh73a0: Update CMT clockevent rating to 80 sh-pfc: r8a7779: Don't group USB OVC and PENC pins Signed-off-by: Olof Johansson <olof@lixom.net>
