+* Qualcomm QCA7000
+
+The QCA7000 is a serial-to-powerline bridge with a host interface which could
+be configured either as SPI or UART slave. This configuration is done by
+the QCA7000 firmware.
+
+(a) Ethernet over SPI
+
+In order to use the QCA7000 as SPI device it must be defined as a child of a
+SPI master in the device tree.
+
+Required properties:
+- compatible : Should be "qca,qca7000"
+- reg : Should specify the SPI chip select
+- interrupts : The first cell should specify the index of the source
+ interrupt and the second cell should specify the trigger
+ type as rising edge
+- spi-cpha : Must be set
+- spi-cpol : Must be set
+
+Optional properties:
+- interrupt-parent : Specify the pHandle of the source interrupt
+- spi-max-frequency : Maximum frequency of the SPI bus the chip can operate at.
+ Numbers smaller than 1000000 or greater than 16000000
+ are invalid. Missing the property will set the SPI
+ frequency to 8000000 Hertz.
+- local-mac-address : see ./ethernet.txt
+- qca,legacy-mode : Set the SPI data transfer of the QCA7000 to legacy mode.
+ In this mode the SPI master must toggle the chip select
+ between each data word. In burst mode these gaps aren't
+ necessary, which is faster. This setting depends on how
+ the QCA7000 is setup via GPIO pin strapping. If the
+ property is missing the driver defaults to burst mode.
+
+SPI Example:
+
+/* Freescale i.MX28 SPI master*/
+ssp2: spi@80014000 {
+ #address-cells = <1>;
+ #size-cells = <0>;
+ compatible = "fsl,imx28-spi";
+ pinctrl-names = "default";
+ pinctrl-0 = <&spi2_pins_a>;
+ status = "okay";
+
+ qca7000: ethernet@0 {
+ compatible = "qca,qca7000";
+ reg = <0x0>;
+ interrupt-parent = <&gpio3>; /* GPIO Bank 3 */
+ interrupts = <25 0x1>; /* Index: 25, rising edge */
+ spi-cpha; /* SPI mode: CPHA=1 */
+ spi-cpol; /* SPI mode: CPOL=1 */
