Hi,
Looks like commit effe02710335 ("mfd: syscon: Set regmap max_register
in of_syscon_register") somehow breaks smsc911x GPIO interrupt for
me at least on omap3:
irq 241: nobody cared (try booting with the "irqpoll" option)
CPU: 0 PID: 1 Comm: swapper/0 Not tainted 4.5.0-rc3-next-20160212 #864

I'm not seeing the connection between regmap and GPIO, so no
idea what goes wrong here.
