Re: [PATCH] mfd: stmpe: Pull IRQ GPIO number from DT during DT-based probe

This is a new DT binding and you haven't provided any documentation for it.

Also, there is no reason for the binding to exist.

Lots of drivers use GPIO pins as IRQs.
Right, this can be removed and only the 'irq-gpios' can be kept around. What do 
you say?
I don't like it to be honest.

How many GPIOs does the STMPE driver need?
