[PATCH 2/2] drm/tegra: hub: Register child devices

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

 



From: Thierry Reding <treding@xxxxxxxxxx>

In order to remove the dependency on the simple-bus compatible string,
which causes the OF driver core to register all child devices, make the
display-hub driver explicitly register the display controller children.
