This patch series is partially based on a series Jerome Brunet submitted about half a year ago. Due to open questions this series never made it to mainline, see https://patchwork.kernel.org/patch/9384431/ This new attempt uses GPIOLIB_IRQCHIP resulting in less needed code. The series was successfully tested on a Odroid-C2. Changes in v2: - separate the GPIO IRQ controller from the pinctrl driver - minor improvements to the GPIO IRQ controller Changes in v3: - replace the request_irq based allocation of parent irq's with chained irq handling, this also fixes the spurious interrupts issue and allows to remove the workaround code. Last but not least the parent irq's are no longer visible in /proc/interrupts. - minor improvements to the GPIO IRQ controller Changes in v4: - separate the gpio-independent interrupt controller part and make it a driver under drivers/irqchip Changes in v5: - smaller changes based on review comments - split DT patches per ARM / ARM64 Changes in v6: - based on suggestion by Rob Herring: rename DT property parent-interrupts to interrupts Changes in v7: - remove patch 1 as it was applied to the pinctrl tree already - add patch 5 as prerequisite for reworked patch 6 - remove IRQ_TYPE_EDGE_BOTH support from patch 6 Heiner Kallweit (7): irqchip: add Amlogic Meson GPIO irqchip driver dt-bindings: add Amlogic Meson GPIO interrupt-controller DT binding documentation ARM: dts: meson: add GPIO interrupt-controller support ARM64: dts: meson: add GPIO interrupt-controller support gpiolib: export gpiochip_irq_reqres and gpiochip_irq_relres pinctrl: meson: add support for GPIO interrupts pinctrl: meson: update DT binding documentation ARM: dts: meson: mark gpio controllers as interrupt controllers ARM64: dts: meson: mark gpio controllers as interrupt controllers .../amlogic,meson-gpio-intc.txt | 26 ++ .../devicetree/bindings/pinctrl/meson,pinctrl.txt | 4 + arch/arm/boot/dts/meson8.dtsi | 12 + arch/arm/boot/dts/meson8b.dtsi | 12 + arch/arm64/boot/dts/amlogic/meson-gx.dtsi | 8 + arch/arm64/boot/dts/amlogic/meson-gxbb.dtsi | 4 + arch/arm64/boot/dts/amlogic/meson-gxl.dtsi | 4 + drivers/gpio/gpiolib.c | 6 +- drivers/irqchip/Kconfig | 5 + drivers/irqchip/Makefile | 1 + drivers/irqchip/irq-meson-gpio.c | 295 +++++++++++++++++++++ drivers/pinctrl/Kconfig | 1 + drivers/pinctrl/meson/pinctrl-meson.c | 176 +++++++++++- include/linux/gpio/driver.h | 3 + 14 files changed, 554 insertions(+), 3 deletions(-) create mode 100644 Documentation/devicetree/bindings/interrupt-controller/amlogic,meson-gpio-intc.txt create mode 100644 drivers/irqchip/irq-meson-gpio.c -- 2.13.1 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
