The GPIO controller of Hisilicon hip04 Soc uses the IP from Sysnopsis,
gpio-dwapb.c can be reused to support this GPIO controller. This patch
adds related configure item in hisi_defconfig.

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.

As it only patches arch/arm it's really an ARM SoC business,
but for what it's worth:
