Subject: [PATCH V2 0/2] irqchip: add NXP INTMUX interrupt controller

Hi Marc,

   Registering domain for each channel is indeed a bit unreasonable, I have
changed the driver to support only one channel (channel 0 by default) as
muti-channels is designed to route interrupt to different cores. 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
