Subject: [PATCH RESEND 1/9] dt-bindings: usb: mtk-xhci: add optional property to disable usb2 ports
Date: Tue, 17 Aug 2021 16:36:21 +0800	[thread overview]
Message-ID: <1629189389-18779-1-git-send-email-chunfeng.yun@mediatek.com> (raw)

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.
