The most of devicetree has the following USB node structure.
The controller node is placed as a child node of the glue node.
Current dwc3-generic driver works on this premise.
glue {
/* glue node */
usb {
/* controller node */
};
};
However, UniPhier original devicetree has the following USB node structure.
The controller node is separately placed from the glue node.
usb {
/* controller node */
};
glue {
/* glue node */
};
In dwc_glue_bind(), this patch provides .glue_get_ctrl_dev() callback to
get such a controller node and binds the driver related to the node.
If this callback isn't defined, dwc_glue_bind() looks for the controller
nodes from the child nodes, as before.
