@@ -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>;

+ <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";
