This is quite interesting. Currently the PHY muxing feature for the MT7530 switch looks for some fake ethernet-phy definitions on the mdio-bus where the switch is also defined. Looking at the binding here, there will be an mdio node under the switch node. This could be useful to define the ethernet-phys for PHY muxing here instead, so we don't waste the register addresses on the parent mdio-bus for fake things. It looks like this should work right out of the box. I will do some tests. Are there any examples as to what to configure on the switch PHYs with this change? > > Signed-off-by: David Bauer > --- > .../devicetree/bindings/net/dsa/mediatek,mt7530.yaml | 6 ++++++ > 1 file changed, 6 insertions(+) > > diff --git a/Documentation/devicetree/bindings/net/dsa/mediatek,mt7530.yaml b/Documentation/devicetree/bindings/net/dsa/mediatek,mt7530.yaml > index e532c6b795f4..50f8f83cc440 100644 > --- a/Documentation/devicetree/bindings/net/dsa/mediatek,mt7530.yaml > +++ b/Documentation/devicetree/bindings/net/dsa/mediatek,mt7530.yaml > @@ -128,6 +128,12 @@ properties: > See Documentation/devicetree/bindings/regulator/mt6323-regulator.txt for > details for the regulator setup on these boards. > > + mdio: > + $ref: /schemas/net/mdio.yaml# > + unevaluatedProperties: false > + description: > + Node for the internal MDIO bus connected to the embedded ethernet-PHYs. Please set this property as false for mediatek,mt7988-switch as it doesn't use MDIO. Arınç
