From mboxrd@z Thu Jan 1 00:00:00 1970 From: Mans Rullgard Subject: [PATCH 1/2] dt-bindings: usb: add non-removable-ports hub property Date: Thu, 28 Feb 2019 18:45:39 +0000 Message-ID: <20190228184540.24570-1-mans@mansr.com> Mime-Version: 1.0 Content-Transfer-Encoding: 8bit Return-path: Sender: linux-kernel-owner@vger.kernel.org To: Greg Kroah-Hartman , Rob Herring , Mark Rutland Cc: linux-usb@vger.kernel.org, devicetree@vger.kernel.org, linux-kernel@vger.kernel.org List-Id: devicetree@vger.kernel.org Add a non-removable-ports property that lists the hardwired downstream ports of a hub. Although hubs can provide this information, they are not always configured correctly. An alternate means of indicating this for built-in USB devices is thus useful.
