Cygnus has 3 GPIO controllers: 1) the ASIU GPIO; 2) the chipCommonG GPIO; and 3) the ALWAYS-ON GPIO. All 3 types of GPIO controllers are supported by the same Cygnus GPIO driver Changes from v4: - Use DT property "linux,gpio-base" to define GPIO base number - factorize common code to improve code readability and reduce code size - remove "bcm_" prefix on function and struct names - improve debugging prints - default GPIO_BCM_CYGNUS to y in Kconfig (it still depends on ARCH_BCM_CYGNUS). This way we do not need to select it from the arch/arm/mach-bcm/Kconfig - Get rid of redundant MAINTAINER entry for this driver. It will be maintained by Broadcom iProc/Cygnus maintainers - Update device tree document based on driver changes Changes from v3: - Fix dt property tpyo - Fix incorrect GPIO compatible ID in device tree binding document example Changes from v2: - Consolidate different compatible IDs into "brcm,cygnus-gpio" - Get rid of redundant "no-interrupt" property Changes from v1: - Get rid of inline qualifier - Get rid of redundant check in the ISR - Other minor fixes to imrove code readability Ray Jui (3): gpio: Cygnus: define Broadcom Cygnus GPIO binding gpio: Cygnus: add GPIO driver ARM: dts: enable GPIO for Broadcom Cygnus .../devicetree/bindings/gpio/brcm,cygnus-gpio.txt | 87 +++ arch/arm/boot/dts/bcm-cygnus.dtsi | 33 ++ drivers/gpio/Kconfig | 12 + drivers/gpio/Makefile | 1 + drivers/gpio/gpio-bcm-cygnus.c | 613 ++++++++++++++++++++ 5 files changed, 746 insertions(+) create mode 100644 Documentation/devicetree/bindings/gpio/brcm,cygnus-gpio.txt create mode 100644 drivers/gpio/gpio-bcm-cygnus.c -- 1.7.9.5
