[PATCH v2 02/13] dt-bindings: usb: mtu3: add optional property to disable usb2 ports

From: Chunfeng Yun
Date: Fri Jun 18 2021 - 05:30:43 EST

Add support to disable specific usb2 host ports, it's useful when
a usb2 port is disabled on some platforms, but enabled on others for
the same SoC, another case is that the different package may support
different number of ports.
