[PATCH v5 0/3] ARM: bcm281xx: GPIO driver

["Markus Mayer" <markus.mayer@linaro.org>]

This patch series adds the GPIO driver, and its device tree bindings,
for the Broadcom bcm281xx family of chips.

Changes since v4:

- Added "brcm,bcm11351-gpio" to compatible value in device tree binding
- Added references to other device tree documentation
- Explicitly mention 1:1 mapping between GPIO banks and IRQs.
- Select driver in Kconfig, but don't depend on ARCH_BCM & don't default y
- Changed hex numbers to lower case
- Removed irq_base/irq_alloc_descs()/irq_free_descs()
- Added kona_gpio to struct bcm_kona_gpio_bank in lieu of reg_base, so
  interrupt handler can access irq_domain
- Removed bcm_kona_count_irq_resources() and switched to using
  of_irq_count()
- Switched interrupt handler to use irq_find_mapping() instead of
  gpio_to_irq()
- Print no error message if devm_kzalloc() fails
- Don't check return value of platform_get_resource()
- Check for maximum bank number
- Use devm_ioremap_resource() instead of devm_request_and_ioremap()
- Use bit operations rather than spelling out bit shifts
- Added a loop to interrupt handler, so it'll handle IRQs that happened
  during IRQ processing
- Some formatting clean-up
