++Lantiq SoC ASC serial controller
++
++Required properties:
++- compatible : Should be "lantiq,asc"
++- reg : Address and length of the register set for the device
++- interrupts: the 3 (tx rx err) interrupt numbers. The interrupt specifier
++ depends on the interrupt-parent interrupt controller.
++
++Example:
++
++asc1: serial@E100C00 {
++ compatible = "lantiq,asc";
++ reg = <0xE100C00 0x400>;
++ interrupt-parent = <&icu0>;
++ interrupts = <112 113 114>;
++};
