Subject: [PATCH v5 6/9] dt/bindings: drm/bridge: it6505: Add mode-switch support
Date: Wed, 22 Jun 2022 17:34:35 +0000 [thread overview]
Message-ID: <20220622173605.1168416-7-pmalani@chromium.org> (raw)
In-Reply-To: <20220622173605.1168416-1-pmalani@chromium.org>
From: Pin-Yen Lin <treapking@chromium.org>
ITE IT6505 can be used in systems to switch USB Type-C DisplayPort
alternate mode lane traffic between 2 Type-C ports.
Update the binding to accommodate this usage by introducing a switch
property.
