I have concerns about this series.

I am worried that joining the banks into one gpio_chip makes it
impossible for you GPIOLIB_IRQCHIP. Usually that is possible and
preferrable when using a chained handler if e.g. one bank has
one IRQ line.

But overall that depends on how the IRQs map on this hardware.
Can you describe how the GPIO IRQs work on the PXA27x?
