Hip04 uses synopsis' GPIO IP, and we use the dwapb GPIO driver here. This series add the corresponding dts. The 3/4 patch supports to find GPIO base number in increasing order, if gpio-number-forward is defined in related dts nodes. If there are some GPIO controllers in one Soc, all related GPIO dts node should contain gpio-number-forward property. If not, error will come out. 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: - http://www.spinics.net/lists/devicetree/msg60324.html Zhou Wang (4): ARM: hip04: add GPIO configure in hisi_defconfig ARM: dts: hip04: add GPIO pieces gpio: Add find base in a increasing order Documentation: dt: gpio: Add gpio-number-forward property in snps gpio binding doc .../devicetree/bindings/gpio/snps-dwapb-gpio.txt | 2 + arch/arm/boot/dts/hip04.dtsi | 79 ++++++++++++++++++++ arch/arm/configs/hisi_defconfig | 3 + drivers/gpio/gpiolib.c | 63 +++++++++++++--- 4 files changed, 138 insertions(+), 9 deletions(-) -- 1.7.9.5
