ARM: hip04: add GPIO support

Quoted 37 lines · 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. The default value of ARCH_NR_GPIOS is used to find gpio base here.

Now this patchset is based on v4.0-rc5

Change in v6:
- Change E-mail address in signed-off-by to "wangzhou1 at hisilicon.com" Change in v5:
- Base on v3.19-rc1
- Just use default value of ARCH_NR_GPIOS to find gpio base. Remove the new added patch(3/4) in v4.
Change in v4:
- Delete "default 128 if ARCH_HIP04" in arch/arm/Kconfig
- add a new patch to support find GPIO base number in increasing order
- add gpio-number-forward property in snps gpio binding doc Change in v3:
- Move CONFIG_GPIO_DWAPB to hisi_defconfig
- Add CONFIG_GPIOLIB, CONFIG_GPIO_SYSFS in hisi_defconfig Change in v2:
- Add select GPIO_DWAPB in arch/arm/mach-hisi/Kconfig

Link for v3:
