After adding the .select callback, we can assign an interrupt to one of irq domains from interrupt specifier. Thanks a lot. ChangeLogs: V2->V3: *impletement .xlate and .select callback. 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.
