I don't see any switch-related driver, nor any userspace (what I have is an extremely minimal OpenWRT userspace that has hardly more than busybox). This is all I see: root@OpenWrt:/# find /sys -name registers /sys/kernel/debug/usb/ohci/0000:00:0e.1/registers /sys/kernel/debug/usb/ohci/0000:00:0e.0/registers /sys/kernel/debug/regmap/dummy-bus@c4000000/registers Thanks, M. -- Without deviation from the norm, progress is not possible. _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
