Hmm, that will require the clock-input-name be same as the second
parameter of clk_get() - con_id, which may have been named to some
string not suitable for clock-input-name.  For those case, we will
probably need to change the drivers to rename the con_id?  Or just
force the clock-input-name to be that improper con_id string?
