Can you please split the content into "converting to clk_bulk" (see
additional comment below) and "add rk3576" please?

That would make the patch a lot cleaner.

Doesn't this create an imbalance - with the missing put?
I think ideally just define clk_bulk_data structs for the
1-clock and 3-clock variant, attach that to the device-data
and then use the regular devm_clk_bulk_get ?

That way you can then retrieve the clock from that struct?


Thanks
