The driver is able to do read/write and allows GPIO to be a interrupt controller. Tested on Altera GHRD on interrupt handling and IO. v9: Removed duplicated initialization on set_type using temporals to improve code readability in calling generic_handle_irq Using ?: ternary to reduce code size v8: Using for_each_set_bit added const for struct definition removed naggy pr_err sort alpha header remove unused macros use fixed width data types instead of unsigned long whitespace issue fixes removed _relaxed function for better compatibility across different CPU changed irq_create_mapping to platform_get_irq updated implementation to use gpiochip_irqchip_add reserve interrupt-cells number 2 in device tree binding for future use remove confusing sections on devicetree bindings Added tristate Kconfig help text v7: used dev_warn instead of pr_warn clean up unnecesarry if else indentation v6: Added irq_startup and irq_shutdown changed bitwise clamping style cleanup bitwise operation to improve readability change naming of mapped irqs from virq to mapped_irq v5: dispose irq_domain mapping correctly update optional binding description in binding docs v4: added vendor prefix to devicetree binding for IP specific properties using MMIO GPIO helper library instead of manually map PIO to memory altera_gpio_chip inline struct documentation to kerneldoc using dev_ print to print a better failure message v2, v3: Do not reference NO_IRQ Updated irq_set_type to only allow the hardware configured irq type Tien Hock Loh (2): drivers/gpio: Altera soft IP GPIO driver device tree binding drivers/gpio: Altera soft IP GPIO driver .../devicetree/bindings/gpio/gpio-altera.txt | 43 +++ MAINTAINERS | 6 + drivers/gpio/Kconfig | 8 + drivers/gpio/Makefile | 1 + drivers/gpio/gpio-altera.c | 405 +++++++++++++++++++++ 5 files changed, 463 insertions(+) create mode 100644 Documentation/devicetree/bindings/gpio/gpio-altera.txt create mode 100644 drivers/gpio/gpio-altera.c -- 1.7.11.GIT -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
