Detailed Description

Devicetree macros for the Infineon XMC4xxx interrupt controller.

Macros for encoding the ERU (Event Request Unit) line mapping cells used with the infineon,xmc4xxx-intc compatible interrupt controller. XMC4XXX_INTC_SET_LINE_MAP() packs the GPIO port and pin, the ERU input source eru_src and the ERU output line into a single mapping value; the matching XMC4XXX_INTC_GET_* accessors extract each field.

&some_device {
        interrupt-names = "rx";
        interrupts = <XMC4XXX_INTC_SET_LINE_MAP(0, 1, 0, 0) 0>;
