Lee Jones 3113e67902 gpio: Enable the tc3298x GPIO expander driver for Device Tree
Here we provide a means to probe and extract vital information
from Device Tree when booting with it enabled. Without this
patch sub-devices wouldn't be able to reference the tc3589x-gpio
expander from Device Tree.

Lee Jones efe4c9496a gpio: Provide the tc3589x GPIO expander driver with an IRQ domain
In preparation for Device Tree enablement all IRQ controllers
should control their own IRQ domain. This patch provides just
that for the tc3589x GPIO expander.

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
