From 51018cde5b55b7b0d65af0d363531cddd360fe11 Mon Sep 17 00:00:00 2001 From: Chunfeng Yun Date: Tue, 17 Aug 2021 16:36:21 +0800 Subject: dt-bindings: usb: mtk-xhci: add optional property to disable usb2 ports 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.
