Paul Gortmaker bb207ef1e8 drivers/gpio: Fix drivers who are implicit users of module.h
A pending cleanup will mean that module.h won't be implicitly
everywhere anymore.  Make sure the modular drivers in gpio
are actually calling out for <module.h> explicitly in advance.

Tomoya MORINAGA 2824bc9c38 gpio-pch: Use NUMA_NO_NODE not GFP_KERNEL
Currently, GFP_KERNEL is used as parameter of irq_alloc_descs like below.

          irq_base = irq_alloc_descs(-1, IOH_IRQ_BASE, num_ports[j],
                                     GFP_KERNEL);

This is not true.
So, this patch uses NUMA_NO_NODE not GFP_KERNEL.

Tomoya MORINAGA e98bed7f0f gpio-pch: Save register value in suspend()
Currently, when suspend is occurred, register im0/1 and gpio_use_sel are not
saved.
This patch modifies so that register im0/1 and gpio_use_sel are saved.

Tomoya MORINAGA d4260e6ddd gpio-pch: modify gpio_nums and mask
Currently, the number of GPIO pins is set fixed value(=12).
Also PIN MASK is set as '0xfff'.
However the pins differs by IOH.
This patch sets the value correctly.

Grant Likely c103de2404 gpio: reorganize drivers
Sort the gpio makefile and enforce the naming convention gpio-*.c for
gpio drivers.

v2: cleaned up filenames in Kconfig and comment blocks
v3: fixup use of BASIC_MMIO to GENERIC_GPIO for mxc
