UART) into the existing document.

(b) Ethernet over UART
In order to use the QCA7000 as UART slave it must be defined as a child of a
UART master in the device tree. It is possible to preconfigure the UART
settings of the QCA7000 firmware, but it's not possible to change them during
runtime.
Required properties:
- compatible : Should be "qca,qca7000"
Optional properties:
- local-mac-address : see ./ethernet.txt
- current-speed : current baud rate of QCA7000 which defaults to 115200
if absent, see also ../serial/slave-device.txt
UART Example:
/* Freescale i.MX28 UART */
auart0: serial@8006a000 {
compatible = "fsl,imx28-auart", "fsl,imx23-auart";
reg = <0x8006a000 0x2000>;
pinctrl-names = "default";
pinctrl-0 = <&auart0_2pins_a>;
status = "okay";
qca7000: ethernet {
compatible = "qca,qca7000";
local-mac-address = [ A0 B0 C0 D0 E0 F0 ];
current-speed = <38400>;
};
};
