(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>;

	};

};
