Subject: [PATCH v8 04/11] dt-bindings: drm/aux-bus: Add an example
Date: Mon, 24 May 2021 17:01:52 -0700 [thread overview]
Message-ID: <20210524165920.v8.4.I79c7ed8815a07d285dd3b38e680e980d1024dbf1@changeid> (raw)
In-Reply-To: <20210525000159.3384921-1-dianders@chromium.org>
Now that we have an eDP controller that lists aux-bus, we can safely
add an example to the aux-bus bindings.
NOTE: this example is just a copy of the one in the 'ti-sn65dsi86'
one. It feels useful to have the example in both places simply because
it's important to document the interaction between the two bindings in
both places.
Signed-off-by: Douglas Anderson <dianders@chromium.org>

Changes in v8:
- Separate DP AUX bus binding is new for v8.
