-* UART (Universal Asynchronous Receiver/Transmitter)
-
-Required properties:
-- compatible : one of:
- - "ns8250"
- - "ns16450"
- - "ns16550a"
- - "ns16550"
- - "ns16750"
- - "ns16850"
- - "nvidia,tegra20-uart"
- - "ibm,qpace-nwp-serial"
- - "serial" if the port type is unknown.
-- reg : offset and length of the register set for the device.
-- interrupts : should contain uart interrupt.
-- clock-frequency : the input clock frequency for the UART.
-
-Optional properties:
-- current-speed : the current active speed of the UART.
-- reg-offset : offset to apply to the mapbase from the start of the registers.
-- reg-shift : quantity to shift the register offsets by.
-- reg-io-width : the size (in bytes) of the IO accesses that should be
- performed on the device. There are some systems that require 32-bit
- 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.
-
-Example:
-
- uart@80230000 {
- compatible = "ns8250";
- reg = <0x80230000 0x100>;
- clock-frequency = <3686400>;
- interrupts = <10>;
- reg-shift = <2>;
- };
