Subject: [PATCH 1/1] dt-bindings: net: convert qca,qca7000.txt yaml format
Convert qca,qca7000.txt yaml format.
Additional changes:
- add refs: spi-peripheral-props.yaml, serial-peripheral-props.yaml and
ethernet-controller.yaml.
- simple spi and uart node name.
- use low case for mac address in examples.

-* 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:
-- 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.
-- 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.
-
-The MAC address will be determined using the optional properties
-defined in ethernet.txt.
-
-SPI Example:
-
-/* Freescale i.MX28 SPI master*/
-ssp2: spi@...14000 {
- #address-cells = <1>;
- #size-cells = <0>;
- compatible = "fsl,imx28-spi";
- pinctrl-names = "default";
- pinctrl-0 = <&spi2_pins_a>;
-
- 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 */
- spi-max-frequency = <8000000>; /* freq: 8 MHz */
- local-mac-address = [ A0 B0 C0 D0 E0 F0 ];
- };
-};
-
-(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/serial.yaml
-
-UART Example:
-
-/* Freescale i.MX28 UART */
-auart0: serial@...6a000 {
- compatible = "fsl,imx28-auart", "fsl,imx23-auart";
- reg = <0x8006a000 0x2000>;
- pinctrl-names = "default";
- pinctrl-0 = <&auart0_2pins_a>;
-
- qca7000: ethernet {
- compatible = "qca,qca7000";
- local-mac-address = [ A0 B0 C0 D0 E0 F0 ];
- current-speed = <38400>;
- };
-};
