Subject: drm/tegra: hub: Register child devices
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=a101e3dad8a90a840ccb45e492cd2ef7c01199ea;p=linux.git

drm/tegra: hub: Register child devices

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.
