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.
The question is what exactly is meant by after boot. :) Anyway, if the kernel has no business changing some other PLLs, if there's code for changing them, should it be dropped? regards, Ondrej -------------- next part -------------- A non-text attachment was scrubbed...
