Subject: gpu: host1x: Register child devices
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=ca2030d56bb7b73079f834b10de38ced9cac74a3;p=linux.git

gpu: host1x: 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
host1x driver explicitly register its children.
