System clks are just gates, and thus do not provide any rate operations.
Authorize clk rate change to be propagated to system clk parents.

Just wanted to do a quick sanity check here. Do you really need
CLK_SET_RATE_GATE?

After taking a closer look, I'd say I don't need this flag, because it's
already set on programmable clks, am I right ?

Do you want me to send a new version removing this flag ?

Otherwise these patches look fine.

Regards,
Mike
