[PATCH v6 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. The default value of ARCH_NR_GPIOS is used to find gpio
base here.

I resend this patchset with new E-mail address in signed-off-by.

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
