I had misunderstood Rob's comment in the v3 patch. I had initially provided the relative path to the bindings file ti,phy-gmii-sel.yaml in the v3 patch. When Rob commented "/schemas/phy/..", I misunderstood and thought that I had to point $ref to a generic phy-provider schema present in the dt-schema repo and thus, in this v4 patch, I had updated $ref accordingly. > >> + description: >> + This is the register to set phy mode through phy-gmii-sel driver. > > I don't understand the description. Please focus on the hardware not > some drivers - what is here? Phy for something? I will fix the description, updating it to the following: "Address of the CTRLMMR_ENETx_CTRL registers which are used to configure the phy-mode of the CPSW MAC ports."

You got a comment for it already. Your patch should make > sense on its own. I had defined the property as an array because there are more than one QSGMII main ports for other devices for which I will be posting the patches. I had planned to reuse this property, with "maxItems: 2" in the future patches for other compatibles. However, as suggested by you, I will change the property to a uint32 instead of uint32-array in this series. Later, in my future patches for other devices, I will change it back to a uint32-array when I reuse the property. > >> + else: >> + properties: >> + ti,qsgmii-main-ports: false > > Blank line I will fix this in the v5 series. > >> - if: >> properties: >> compatible: >> @@ -97,7 +125,7 @@ additionalProperties: false >> >> examples: >> - | >> - phy_gmii_sel: phy-gmii-sel@650 { >> + phy_gmii_sel: phy@650 { > > Split cleanup into separate patch. I will do so. Thank you for reviewing the patch. Regards, Siddharth. -- linux-phy mailing list linux-phy@lists.infradead.org https://lists.infradead.org/mailman/listinfo/linux-phy
