Antoine and Rob, I was just doing some testing with USB on a Qualcomm SoC. I followed the instructions in the binding document: Documentation/devicetree/bindings/usb/ci-hdrc-usb2.txt which has a compatible for "qcom,ci-hdrc", and is, in general, for chipidea-based USB controllers. It says in the document that the property usb-phy is deprecated, and to use phys and phy-names instead. However, the Qualcomm driver for this still uses usb-phy. That driver is in: drivers/usb/chipidea/ci_hdrc_msm.c I'm guessing I should update the Qualcomm driver to use phys and phy-names, but wanted to check with you-all to verify that this is the preferred method of getting phys by phandle now. It's either change the driver or make an exception in the binding document, I believe. I presume I should be changing devm_usb_get_phy_by_phandle() to of_phy_get(), but let me know if there's more to it than that. In case I change the driver, do I then update the binding doc to remove the information about the deprecated property, or not?
