You remove ingenic_usb_phy_set_peripheral()=20 and ingenic_usb_phy_set_host(), then add ingenic_usb_phy_init() and=20 ingenic_usb_phy_exit(). Why were the two first functions removed? Just=20 keep these around, and call them from ingenic_usb_phy_set_mode(). That=20 will automatically make the diff much smaller. And by making the diff smaller, we can spot the actual differences.=20 Like how support for PHY_MODE_USB_OTG was added, without any notice. >=20 > -static int ingenic_usb_phy_init(struct usb_phy *phy) > +static int ingenic_usb_phy_power_on(struct phy *phy) > { > - struct jz4770_phy *priv =3D phy_to_jz4770_phy(phy);

> MODULE_AUTHOR("Paul Cercueil "); > MODULE_DESCRIPTION("Ingenic SoCs USB PHY driver"); > +MODULE_ALIAS("jz4770-phy"); So I first thought this generic PHY driver would be a drop-in=20 replacement for the old jz4770-phy driver, that's why I suggested to=20 add the jz4770-phy alias. But it turns out that it's a completely=20 different framework, so we can drop the alias. That also means that this patch, without any change to the JZ4740 MUSB=20 driver, breaks USB on all Ingenic SoCs I can test with. So unless you have a patch to the jz4740-musb driver in this series,=20 you can't remove the old jz4770-phy driver yet. Just modify this patch=20 so that the new generic-PHY driver is added, without removing the old=20 one. It will be much easier to review (one new driver vs lots of +/-=20 lines) and you can move the code around if you want to. Then when the=20 jz4740-musb driver is modified to use the generic PHY framework, the=20 old jz4770-phy driver can be "retired".
