Maybe it is not suitable to put data-lanes in input endpoint. extcon doesn't have output endpoint, so I don't know where to put is better. -----Original Message----- From: Neil Armstrong <neil.armstrong@...aro.org> Sent: Thursday, September 29, 2022 4:40 PM To: Allen Chen (陳柏宇) <allen.chen@....com.tw> Cc: open list:OPEN FIRMWARE AND FLATTENED DEVICE TREE BINDINGS <devicetree@...r.kernel.org>; Kenneth Hung (洪家倫) <Kenneth.Hung@....com.tw>; Jernej Skrabec <jernej.skrabec@...il.com>; Krzysztof Kozlowski <krzysztof.kozlowski+dt@...aro.org>; Jau-Chih Tseng (曾昭智) <Jau-Chih.Tseng@....com.tw>; David Airlie <airlied@...ux.ie>; open list:DRM DRIVERS <dri-devel@...ts.freedesktop.org>; Neil Armstrong <narmstrong@...libre.com>; open list <linux-kernel@...r.kernel.org>; Robert Foss <robert.foss@...aro.org>; Pin-yen Lin <treapking@...omium.org>; Hermes Wu (吳佳宏) <Hermes.Wu@....com.tw>; Rob Herring <robh+dt@...nel.org>; Laurent Pinchart <Laurent.pinchart@...asonboard.com>; Andrzej Hajda <andrzej.hajda@...el.com>; Jonas Karlman <jonas@...boo.se> Subject: Re: [PATCH v2 1/2] dt-bindings: it6505: add properties to restrict output bandwidth Hi, On 29/09/2022 03:44, allen wrote: > From: allen chen <allen.chen@....com.tw> > > Add properties to restrict dp output data-lanes and clock. > > Signed-off-by: Pin-Yen Lin <treapking@...omium.org> > Signed-off-by: Allen Chen <allen.chen@....com.tw> > --- > .../devicetree/bindings/display/bridge/ite,it6505.yaml | 10 ++++++++++ > 1 file changed, 10 insertions(+) > > diff --git > a/Documentation/devicetree/bindings/display/bridge/ite,it6505.yaml > b/Documentation/devicetree/bindings/display/bridge/ite,it6505.yaml > index 833d11b2303a..62b9f2192202 100644 > --- a/Documentation/devicetree/bindings/display/bridge/ite,it6505.yaml > +++ b/Documentation/devicetree/bindings/display/bridge/ite,it6505.yaml > @@ -52,6 +52,14 @@ properties: > maxItems: 1 > description: extcon specifier for the Power Delivery > > + data-lanes: > + maxItems: 1 > + description: restrict the dp output data-lanes with value of 1-4 Can't you use the data-lanes property in the first port endpoint ?
