[PATCH v2 0/2] ARM: hip04: add GPIO support

[Zhou Wang]

This series add the support for the GPIOs of Hisilicon Soc hip04. Hip04 uses
synopsis' GPIO IP, and we use the dwapb GPIO driver here. This series add the
corresponding dts.

Change in v2:
- Add select GPIO_DWAPB in arch/arm/mach-hisi/Kconfig

Zhou Wang (2):
  ARM: hip04: set ARCH_NR_GPIO to 128
  ARM: dts: hip04: add GPIO pieces

[PATCH v2 1/2] ARM: hip04: set ARCH_NR_GPIO to 128

[Zhou Wang]

Set ARCH_NR_GPIO for Hisilicon Soc Hip04, which has 4 GPIO
controllers with 32 GPIOs each.

[PATCH v2 2/2] ARM: dts: hip04: add GPIO pieces

[Zhou Wang]

Hisilicon Soc hip04 has four GPIO controllers, each one has 32
GPIOs and can be configured to be an interrupt controller.The GPIO
controllers are compatible with the snps,dw-apb-gpio driver.
This patch add the corresponding device tree nodes.
