REGRESSION pinctrl armada-37xx

[Marek Behun <marek.behun@xxxxxx>]

Hello,
I am encountering a regression caused by commit 
06e26b75f5e6 ("pinctrl: mvebu: armada-37xx: use use platform api").

The pinctrl driver won't load with error
[    2.374219] armada-37xx-pinctrl d0013800.pinctrl: invalid or no IRQ
[    2.381309] armada-37xx-pinctrl d0018800.pinctrl: invalid or no IRQ

I just spent several hours finding this, because it caused some weird
bugs for devices using gpio as irq source.

Either platform_irq_count should get fixed or we should revert this
commit.
