[PATCH v4 0/4] GPIO support for BRCMSTB

[Gregory Fong]

Adds interrupt support for the GPIO controller (UPG GIO) used on Broadcom's
various BRCMSTB SoCs (BCM7XXX and others).  For all existing hardware, this
block hooks up to the BCM7120 L2 IRQ controller and so will require
CONFIG_BCM7120_L2_IRQ=y.

New in v4:
- add nodes for the BRCMSTB GPIO controller to the BCM7445 dts file
- a few improvements suggested by Linus Walleij on v3
- remove unused 'irq' argument to brcmstb_gpio_irq_bank_handler()

The following are not included in this patchset:
- Initial device tree bindings (merged from v1 to GPIO tree)
- Initial GPIO support w/o interrupts (merged from v2 to GPIO tree)
- ARM Kconfig changes (merged from v2 to arm-soc tree)
- fix for null ptr deref in driver remove (merged from v3)

Previous versions:
v1: https://lkml.org/lkml/2015/5/6/199
v2: https://lkml.org/lkml/2015/5/28/853
v3: https://lkml.org/lkml/2015/6/17/960
