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. 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 v4: - http://www.spinics.net/lists/arm-kernel/msg383883.html Link for v3: - http://www.spinics.net/lists/devicetree/msg60324.html Zhou Wang (2): ARM: hip04: add GPIO configure in hisi_defconfig ARM: dts: hip04: add GPIO pieces arch/arm/boot/dts/hip04.dtsi | 77 +++++++++++++++++++++++++++++++++++++++ arch/arm/configs/hisi_defconfig | 1 + 2 files changed, 78 insertions(+) -- 1.7.9.5 ^ permalink raw reply [flat|nested] 3+ messages in thread
