The Exynos2200 SoC has a USB controller PHY, which acts as an intermediary between a USB controller (typically DWC3) and other PHYs (UTMI, PIPE3). Add a dt-binding schema for it.

You have undocumented dependencies which prevent merging this file. First, dependencies have to be clearly expressed. Second, you should rather decouple the code from header dependencies, otherwise this cannot be merged for current release (just use clocks with long names, without IDs).

Isn't this the same as usbdrd phy? see: samsung,usb3-drd-phy.yaml I think there is no PHY between DWC3 and UTMI/PIPE. There is a PHY controller (so the samsung,usb3-drd-phy.yaml) which we call here the phy. Best regards, Krzysztof
