Subject: [PATCH v7 10/10] arm64: dts: qcom: sc7180-trogdor: Move panel under the bridge chip
Date: Mon, 17 May 2021 13:09:07 -0700 [thread overview]
Message-ID: <20210517130450.v7.10.Ibdb7735fb1844561b902252215a69526a14f9abd@changeid> (raw)
In-Reply-To: <20210517200907.1459182-1-dianders@chromium.org>
Putting the panel under the bridge chip (under the aux-bus node)
allows the panel driver to get access to the DP AUX bus, enabling all
sorts of fabulous new features.
While we're at this, get rid of a level of hierarchy for the panel
node. It doesn't need "ports / port" and can just have a "port" child.
For Linux, this patch has a hard requirement on the patches adding DP
AUX bus support to the ti-sn65dsi86 bridge chip driver. See the patch
("drm/bridge: ti-sn65dsi86: Add support for the DP AUX bus").
Signed-off-by: Douglas Anderson <dianders@chromium.org>

Changes in v7:
- Panel now under bridge chip instead of getting a link to ddc-i2c
