Since this is really specific, I guess you could simply make the clk_ops for the nkmp clocks public, and just re-implement set_rate using that logic.I would argue that this may be necessary for other PLL clocks too, if you can get out of bounds output frequency, by changing the dividers too early or too late. So perhaps this code should be generalized for other PLL clocks too, instead.
The documentation says that only the CPU and DDR PLLs can be dynamically changed after boot. -- Ken ar c'hentañ | ** Breizh ha Linux atav! ** Jef | http://moinejf.free.fr/
