+* NXP LPC32xx SoC High Speed UART
+
+Required properties:
+- compatible: Should be "nxp,lpc3220-hsuart"
+- reg: Should contain registers location and length
+- interrupts: Should contain interrupt
+
+Example:
+
+ uart1: serial@40014000 {
+ compatible = "nxp,lpc3220-hsuart";
+ reg = <0x40014000 0x1000>;
+ interrupts = <26 0>;
+ };
accesses to the UART (e.g. TI davinci).
- used-by-rtas : set to indicate that the port is in use by the OpenFirmware
RTAS and should not be registered.
+- no-loopback-test: set to indicate that the port does not implements loopback
+ test mode
Example:
