Nevermind, turns out I didn't apply the CLK_IGNORE_UNUSED PATCH. If I
actually apply it, I have it working on top of linux-next. However, it
seems to have some issues with the nonboot CPUs resuming:
[ 11.319833] Enabling non-boot CPUs ...
[ 12.319134] CPU1: failed to come online
[ 12.319235] Error taking CPU1 up: -5
[ 13.319137] CPU2: failed to come online
[ 13.319209] Error taking CPU2 up: -5
[ 14.319133] CPU3: failed to come online
[ 14.319224] Error taking CPU3 up: -5
Are you guys seeing all the non-boot CPUs coming up? They fail to come
online, but the /sys/devices/.../cpu?/online reports that they are
online, which means the next attempt to hotplug them will probably BUG().
Also, If I turn off the switcher (enabled by default exynos_defconfig),
resume still has problems bringing all the nonboot CPUs online, and then
has a bunch of I2C errors[1].
And one more..., if I try enabling CPUidle[1] with exynos_defconfig, S2R
causes a reboot (seems to be on resume.)
