I thought usb_phy_*() stuff would be deprecated and we should use phy framework instead i.e. phy_init() and friends. In fact usb_add_hcd() is already handling the phy for us. So I'm in favor of getting rid of commit 7b8ef22ea547b80475ac7feab06fb15e0fc143d8 (usb: xhci: plat: Add USB phy support) cheers, -roger -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
