Hello Russell,

Thanks a lot for your suggestion.

Yes I know that con_id is the device specific connection name that is set by the
consumers using the "clock-names" property. But AFAIU the clk_lookup structs
added by clockdev_add() are only used by legacy non-DT drivers which don't set
their clock names and instead is the clock driver the one that set con_id to the
struct clk_init_data .name field.

I see that other drivers do the same, is that wrong as well? What value should
have con_id when registering clkdevs for legacy non-DT drivers?

DT enabled drivers whose devices define their "clock-names" are not affected by
this since the clock lookup is made by matching OF "clock-names" property + and
index.

Best regards,
Javier
