This is the serdev binding for the QCA7000 UART driver (Ethernet over UART).

According to this binding are still some questions:
Where should be the optional hardware flow control defined (at master or slave side)?
Is it okay to have two bindings (qca-qca7000-spi and qca-qca7000-uart) or should they be merged?

+* Qualcomm QCA7000 (Ethernet over UART protocol)
+
+Note: This binding applies in case the QCA7000 is configured as a
+UART slave device. It is possible to preconfigure the UART settings
+of the QCA7000 firmware, which can't be changed during runtime.
+
+Required properties:
+- compatible : Should be "qca,qca7000-uart"
+
+Optional properties:
+- local-mac-address : 6 bytes, Specifies MAC address
+- current-speed : Specifies the serial device speed in
+ bits per second (default = 115200), which is
+ predefined by the QCA7000 firmware configuration
+
+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>;
+ };
+};
