Adding the dt binding yaml for the lan9303 3-port ethernet switch. The microchip lan9354 3-port ethernet switch will also use the same binding. Signed-off-by: Jerry Ray <jerry.ray@xxxxxxxxxxxxx> --- v2->v3: - removed cpu labels - now patching against latest net-next v1->v2: - fixed dt_binding_check warning - added max-speed setting on the switches 10/100 ports. --- .../devicetree/bindings/net/dsa/lan9303.txt | 99 +------------- .../bindings/net/dsa/microchip,lan9303.yaml | 129 ++++++++++++++++++ MAINTAINERS | 8 ++ 3 files changed, 139 insertions(+), 97 deletions(-) create mode 100644 Documentation/devicetree/bindings/net/dsa/microchip,lan9303.yaml diff --git a/Documentation/devicetree/bindings/net/dsa/lan9303.txt b/Documentation/devicetree/bindings/net/dsa/lan9303.txt index 46a732087f5c..8c8fedd1f00e 100644 --- a/Documentation/devicetree/bindings/net/dsa/lan9303.txt +++ b/Documentation/devicetree/bindings/net/dsa/lan9303.txt @@ -1,100 +1,5 @@ SMSC/MicroChip LAN9303 three port ethernet switch ------------------------------------------------- -Required properties: - -- compatible: should be - - "smsc,lan9303-i2c" for I2C managed mode - or - - "smsc,lan9303-mdio" for mdio managed mode - -Optional properties: - -- reset-gpios: GPIO to be used to reset the whole device -- reset-duration: reset duration in milliseconds, defaults to 200 ms - -Subnodes: - -The integrated switch subnode should be specified according to the binding -described in dsa/dsa.txt.
