ChangeLogs: V3->V4: *set IRQ_TYPE_LEVEL_HIGH flag in .xlate callback. *fix comment format. *use an intermediate variable for irq_domain_add_linear(). *disable interrupts before enabling chained interrupt. *disable interrupt in imx_remove() for level interrupt. 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.
