The fixed channel is enough for us. Thanks for your kindly review. ChangeLog: V1->V2: *squash patches: drivers/irqchip: enable INTMUX interrupt controller driver drivers/irqchip: add NXP INTMUX interrupt multiplexer support *remove properity "fsl,intmux_chans", only support channel 0 by default. *delete two unused macros. *align the various field in struct intmux_data. *turn to spin lock _irqsave version. *delete struct intmux_irqchip_data *disable interrupt in probe stage and clear pending status in remove stage Joakim Zhang (2): dt-bindings/irq: add binding for NXP INTMUX interrupt multiplexer drivers/irqchip: add NXP INTMUX interrupt multiplexer support .../interrupt-controller/fsl,intmux.txt | 28 ++ drivers/irqchip/Kconfig | 6 + drivers/irqchip/Makefile | 1 + drivers/irqchip/irq-imx-intmux.c | 240 ++++++++++++++++++ 4 files changed, 275 insertions(+) create mode 100644 Documentation/devicetree/bindings/interrupt-controller/fsl,intmux.txt create mode 100644 drivers/irqchip/irq-imx-intmux.c
