Yes, the same problem has exynos5250-snow.dts. This is less relevant now
after commit f6a8249f9e55 ("pinctrl: exynos: Lock GPIOs as interrupts
when used as EINTs") that moved the pinmux reconfiguration to
.irq_{request,release}_resources() preventing the pads to be reconfigured
as regulator input/output.

But still for correctness we should audit spring / snow and change to 0xf.

Best regards,
Javier
