Hi Paul,

Unfortunately, your commit

commit ca5481c68e9fbcea62bb3c78ae6cccf99ca8fb73
Author: Paul Mundt <lethal@linux-sh.org>

    sh: pfc: Rudimentary pinctrl-backed GPIO support.

breaks system suspend on the Mackerel board (.config attached).  The system
simply doesn't suspend and instead it hangs somewhere while suspending
devices (apparently before running the "late" callbacks).

If the above commit is reverted, system suspend works normally.

Thanks,
Rafael
