The old binding variant (the one covering whole DMU block) was deprecated 3 years ago. Linux kernel was warning when using it for similar amount of time. There aren't any known Northstar devices with bootloader providing DT to operating system. Actually OpenWrt seems to be the only project using this binding and it always appends DTB to kernel. It has switched to the non-deprecated binding years ago. Given there is close to zero chance this breaks anyone's setup it should more than safe to drop this binding variant after 3 years.

To initialize USB 2.0 PHY driver needs to setup PLL correctly.
|
|
To do this it requires passing phandle to the USB PHY reference clock.
