Subject: [PATCH V6 0/2] irqchip: add NXP INTMUX interrupt controller

This patch set adds driver for NXP INTMUX interrupt controller.

ChangeLogs:
V5->V6:
	*fix DTC check failure from binding file.

V4->V5:
	*get number of channels by platform_irq_count() instead of
	'fsl,intmux_chans' property
	*update binding files and remove 'fsl,intmux_chans' property.

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.
	*convert binding to DT schema.

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.

Joakim Zhang (2):
  dt-bindings/irq: add binding for NXP INTMUX interrupt multiplexer
  drivers/irqchip: add NXP INTMUX interrupt multiplexer support
