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. Included is also support for using two parent IRQs in case of IRQ_TYPE_EDGE_BOTH, like in the vendor driver. The series was successfully tested on a Odroid-C2, e.g. with removing polling for SD card insertion/removal from the mmc driver. Known open issues: - location of the irqchip driver and its DT binding documentation 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 Heiner Kallweit (7): pinctrl: meson: add interrupts to pinctrl data pinctrl: meson: document GPIO IRQ DT binding pinctrl: meson: add DT node for GPIO IRQ on Meson GX pinctrl: meson: add DT node for GPIO IRQ on Meson 8 / 8b pinctrl: meson: improve meson_get_bank and export it pinctrl: meson: add support for GPIO interrupts pinctrl: meson: add interrupt controller to GPIO DT nodes .../bindings/gpio/amlogic,meson-gpio-interrupt.txt | 30 ++ .../devicetree/bindings/pinctrl/meson,pinctrl.txt | 4 + arch/arm/boot/dts/meson8.dtsi | 15 + arch/arm/boot/dts/meson8b.dtsi | 15 + arch/arm64/boot/dts/amlogic/meson-gx.dtsi | 13 + arch/arm64/boot/dts/amlogic/meson-gxbb.dtsi | 4 + arch/arm64/boot/dts/amlogic/meson-gxl.dtsi | 4 + drivers/pinctrl/Kconfig | 1 + drivers/pinctrl/meson/Makefile | 2 +- drivers/pinctrl/meson/pinctrl-meson-gxbb.c | 22 +- drivers/pinctrl/meson/pinctrl-meson-gxl.c | 20 +- drivers/pinctrl/meson/pinctrl-meson-irq.c | 320 +++++++++++++++++++++ drivers/pinctrl/meson/pinctrl-meson.c | 62 ++-- drivers/pinctrl/meson/pinctrl-meson.h | 19 +- drivers/pinctrl/meson/pinctrl-meson8.c | 20 +- drivers/pinctrl/meson/pinctrl-meson8b.c | 32 ++- 16 files changed, 502 insertions(+), 81 deletions(-) create mode 100644 Documentation/devicetree/bindings/gpio/amlogic,meson-gpio-interrupt.txt create mode 100644 drivers/pinctrl/meson/pinctrl-meson-irq.c -- 2.13.0 -- 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
