This will require some more thought on the best way to handle (but I'm not asking you to change anything yet).
This constraint comes from function of_clk_get in drivers/of/clock.c:
struct clk *of_clk_get(struct device *dev, const char *id) { [...] dev_dbg(dev, "Looking up %s-clock from device tree\n", id);
snprintf(prop_name, 32, "%s-clock", id ? id : "bus"); prop = of_get_property(dev->of_node, prop_name, &sz); [...] }
The 'id' here is clk_lookup->con_id. If we choose to use some fixed prop name here, the name leaking Linux implementation like 'fec_clk' will not need to be there.
What about fixing the name as 'bus-clock' used by the current implementation, or 'module-clock', or anything you can think of better?
