dt-bindings: serial: Convert lantiq,asc to DT schema 



Convert the Lantiq SoC ASC UART binding to DT schema. There are no such
clock identifier defines nor a user with clocks, so drop the example
with clocks.

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.



Optional properties:

- clocks: Should contain frequency clock and gate clock

- clock-names: Should be "freq" and "asc"



Example:



asc0: serial@16600000 {

	compatible = "lantiq,asc";

	reg = <0x16600000 0x100000>;

	interrupt-parent = <&gic>;

	interrupts = <GIC_SHARED 103 IRQ_TYPE_LEVEL_HIGH>,

		<GIC_SHARED 105 IRQ_TYPE_LEVEL_HIGH>,

		<GIC_SHARED 106 IRQ_TYPE_LEVEL_HIGH>;

	clocks = <&cgu CLK_SSX4>, <&cgu GCLK_UART>;

	clock-names = "freq", "asc";

};



asc1: serial@e100c00 {

	compatible = "lantiq,asc";

	reg = <0xE100C00 0x400>;

	interrupt-parent = <&icu0>;

	interrupts = <112 113 114>;

};
