@ -6,8 +6,23 @@ Required properties:
- 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>;
