-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>;
-};
