[PATCH v10 11/11] arm64: dts: qcom: sc7180-trogdor: Move panel under the bridge chip

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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").
