Do you really need three different bindings here? I believe the recommended approach is to define one binding for the common case, and reuse it for similar SOCs. Additional bindings should only be added if there is some difference in the SOC that requires it. > - reg : Should contain 1 register range (address and length) > - interrupts : Should contain 1 interrupt > @@ -15,6 +18,8 @@ Optional properties: > - phys: phy provider specifier > - phy-names: shall be "usb2-phy" > Refer to phy/phy-bindings.txt for generic phy consumer properties > +- dr_mode: shall be one of "host", "peripheral" and "otg" I don't see where you use 'dr_mode' in any of the DTS files. Are you going to add the uses later? And please us a more descriptive name, such as 'dual-role-mode'. -- Paul -- To unsubscribe from this list: send the line "unsubscribe linux-doc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
