If extcon is a loadable module and rockchip-inno-usb2 is built-in, we get a link failure:
drivers/phy/phy-rockchip-inno-usb2.o: In function `rockchip_usb2phy_probe': phy-rockchip-inno-usb2.c:(.text.rockchip_usb2phy_probe+0x1ec): undefined reference to `extcon_get_edev_by_phandle' phy-rockchip-inno-usb2.c:(.text.rockchip_usb2phy_probe+0x25c): undefined reference to `devm_extcon_dev_allocate' phy-rockchip-inno-usb2.c:(.text.rockchip_usb2phy_probe+0x2a8): undefined reference to `devm_extcon_dev_register' phy-rockchip-inno-usb2.c:(.text.rockchip_usb2phy_probe+0xa28): undefined reference to `extcon_register_notifier'
Adding a hard dependency avoids the problem. Alternatively we could use "depends on EXTCON || !EXTCON" to allow building with extcon disabled completely, but the other PHY drivers with extcon support also just have a dependency, so this is more consistent.
