Subject: [PATCH 02/23] dt-bindings: usb: mtu3: add optional property to disable usb2 ports
Date: Tue, 8 Jun 2021 15:57:28 +0800 [thread overview]
Message-ID: <1623139069-8173-3-git-send-email-chunfeng.yun@mediatek.com> (raw)
In-Reply-To: <1623139069-8173-1-git-send-email-chunfeng.yun@mediatek.com>
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.
