    Subject[PATCH v5 15/17] dt-bindings: qca7000: append UART interface to binding
    Date
    This merges the serdev binding for the QCA7000 UART driver (Ethernet over
    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-uart"
    +
    +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-uart";
    + local-mac-address = [ A0 B0 C0 D0 E0 F0 ];
    + current-speed = <38400>;
    + };
    +};
