Add device-tree binding example of the ksz9477 switch managed in i2c mode. Cc: devicetree@vger.kernel.org Signed-off-by: Sergio Paracuellos <sergio.paracuellos@gmail.com> --- Changes v4: - Use one tab formatting properly the binding sample. Changes v3: - No changes. Just resent patches together. Changes v2: - Use generic name for label of the switch and make sure reg and @X have the same value. .../devicetree/bindings/net/dsa/ksz.txt | 51 +++++++++++++++++++ 1 file changed, 51 insertions(+)diff --git a/Documentation/devicetree/bindings/net/dsa/ksz.txt b/Documentation/devicetree/bindings/net/dsa/ksz.txt index 0f407fb371ce..2f276aa42f0b 100644 --- a/Documentation/devicetree/bindings/net/dsa/ksz.txt +++ b/Documentation/devicetree/bindings/net/dsa/ksz.txt@@ -74,3 +74,54 @@ Ethernet switch connected via SPI to the host, CPU port wired to eth0: }; }; }; + +Ethernet switch connected via I2C to the host, CPU port wired to eth0: + + eth0: ethernet@10001000 { + fixed-link { + speed = <1000>; + full-duplex; + }; + }; + + i2c0: i2c@f8008000 { + switch: ksz9897@5f { + compatible = "microchip,ksz9897"; + reg = <5f>; +
I should have said this earlier, but this example doesn't really show anything other than differences in reg and bus-specific properties which are pretty well understood. So I don't really think it is worth adding the example.
