Yes, you can have these compatible strings. But you can also use the PHY ID, e.g. ethernet-phy-idAAAA.BBBB, where AAAA and BBBB are what you find in registers 2 and 3 of the PHY. > Cc: Rob Herring <robh@kernel.org> > Signed-off-by: Anand Moon <linux.amoon@gmail.com> > --- > Documentation/devicetree/bindings/net/ethernet-phy.yaml | 6 +++--- > 1 file changed, 3 insertions(+), 3 deletions(-) > > diff --git a/Documentation/devicetree/bindings/net/ethernet-phy.yaml b/Documentation/devicetree/bindings/net/ethernet-phy.yaml > index 2766fe45bb98..cfc7909d3e56 100644 > --- a/Documentation/devicetree/bindings/net/ethernet-phy.yaml > +++ b/Documentation/devicetree/bindings/net/ethernet-phy.yaml > @@ -33,7 +33,7 @@ properties: > description: PHYs that implement IEEE802.3 clause 22 > - const: ethernet-phy-ieee802.3-c45 > description: PHYs that implement IEEE802.3 clause 45 > - - pattern: "^ethernet-phy-id[a-f0-9]{4}\\.[a-f0-9]{4}$" > + - pattern: "^ethernet-phy-ieee[0-9]{3}\\.[0-9][-][a-f0-9]{4}$" So here you need, in addition to, not instead of. Please test you change on for example imx6ul-14x14-evk.dtsi Andrew

Thanks for letting me know so in the next series, I will try to add the below compatible string as per the description in the dts. compatible = "ethernet-phy-id001c.c916", "ethernet-phy-ieee802.3-c22"; > > Cc: Rob Herring <robh@kernel.org> > > Signed-off-by: Anand Moon <linux.amoon@gmail.com> > > --- > > Documentation/devicetree/bindings/net/ethernet-phy.yaml | 6 +++--- > > 1 file changed, 3 insertions(+), 3 deletions(-) > > > > diff --git a/Documentation/devicetree/bindings/net/ethernet-phy.yaml b/Documentation/devicetree/bindings/net/ethernet-phy.yaml > > index 2766fe45bb98..cfc7909d3e56 100644 > > --- a/Documentation/devicetree/bindings/net/ethernet-phy.yaml > > +++ b/Documentation/devicetree/bindings/net/ethernet-phy.yaml > > @@ -33,7 +33,7 @@ properties: > > description: PHYs that implement IEEE802.3 clause 22 > > - const: ethernet-phy-ieee802.3-c45 > > description: PHYs that implement IEEE802.3 clause 45 > > - - pattern: "^ethernet-phy-id[a-f0-9]{4}\\.[a-f0-9]{4}$" > > + - pattern: "^ethernet-phy-ieee[0-9]{3}\\.[0-9][-][a-f0-9]{4}$" > > So here you need, in addition to, not instead of. > > Please test you change on for example imx6ul-14x14-evk.dtsi > Yes I have gone through the test case. > Andrew - Anand

That's not needed, typically the PHY ID is auto-detected. Before sending a new series, please describe in detail what your problem is. Simply there shouldn't be a need for such a series. As I said: e.g. Odroid-C2 worked fine for me with a mainline kernel. > > compatible = "ethernet-phy-id001c.c916", > "ethernet-phy-ieee802.3-c22"; > >>> Cc: Rob Herring <robh@kernel.org> >>> Signed-off-by: Anand Moon <linux.amoon@gmail.com> >>> --- >>> Documentation/devicetree/bindings/net/ethernet-phy.yaml | 6 +++--- >>> 1 file changed, 3 insertions(+), 3 deletions(-) >>> >>> diff --git a/Documentation/devicetree/bindings/net/ethernet-phy.yaml b/Documentation/devicetree/bindings/net/ethernet-phy.yaml >>> index 2766fe45bb98..cfc7909d3e56 100644 >>> --- a/Documentation/devicetree/bindings/net/ethernet-phy.yaml >>> +++ b/Documentation/devicetree/bindings/net/ethernet-phy.yaml >>> @@ -33,7 +33,7 @@ properties: >>> description: PHYs that implement IEEE802.3 clause 22 >>> - const: ethernet-phy-ieee802.3-c45 >>> description: PHYs that implement IEEE802.3 clause 45 >>> - - pattern: "^ethernet-phy-id[a-f0-9]{4}\\.[a-f0-9]{4}$" >>> + - pattern: "^ethernet-phy-ieee[0-9]{3}\\.[0-9][-][a-f0-9]{4}$" >> >> So here you need, in addition to, not instead of. >> >> Please test you change on for example imx6ul-14x14-evk.dtsi >> > > Yes I have gone through the test case. > >> Andrew > > - Anand >

If you already ran 'make dt_binding_check' and didn't see the above error(s), then make sure 'yamllint' is installed and dt-schema is up to date: pip3 install dtschema --upgrade Please check and re-submit.
