'phy-rockchip-inno-usb2.txt' is updated to yaml, whereby the compatible string 'rockchip,rk3366-usb2phy' was removed, because it's not in use by a dts file, so remove support in the code as well.
Here's a DT using it: https://github.com/rockchip-linux/kernel/blob/develop-4.4/arch/arm64/boot/dts/rockchip/rk3366.dtsi#L820 Please note that although DT bindings happen to be primarily maintained in the upstream kernel tree at the moment, it is mostly as a consequence of Linux being the source of most active development. Bindings should not be considered to be "owned" by upstream Linux since there are many other consumers, both downstream, and in completely different projects like the BSDs. As far as I'm aware there is still a long-term plan to eventually flip the switch and move maintenance to a standalone repo: https://git.kernel.org/pub/scm/linux/kernel/git/devicetree/devicetree-rebasing.git Things like PCI Device IDs and ACPI HIDs aren't even documented as formally as DT bindings, so by the reasoning here we could arguably delete the majority of drivers from the kernel...
