Subject: [PATCH v1 0/2] ARM: hip04: add GPIO support

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.

As the hip04 basic dts has been merged in 3.18 mainline kernel, I just resend
this patchset for review.

Subject: [PATCH v1 2/2] ARM: dts: hip04: add GPIO pieces

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.
