[PATCH RESEND 1/9] dt-bindings: usb: mtk-xhci: add optional property to disable usb2 ports

From: Chunfeng Yun <chunfeng.yun@mediatek.com>
Date: 2021-08-17 08:37:12
Also in: linux-devicetree, linux-mediatek, linux-usb, lkml
Subsystem: mediatek usb3 drd ip driver, open firmware and flattened device tree bindings, the rest, usb subsystem · Maintainers: Chunfeng Yun, Rob Herring, Krzysztof Kozlowski, Conor Dooley, Linus Torvalds, Greg Kroah-Hartman

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.
