Thanks for your help!
The important thing I was missing is that of_clk_get_parent_name()
actually looks up the parent's "clock-output-names" property.
if (of_property_read_string_index(clkspec.np, "clock-output-names", index,
&clk_name) < 0)
clk_name = clkspec.np->name;
but since I had "hardcoded" the clock names, the parent didn't
have a "clock-output-names" property.
Regards.
