If I understand Jisheng correctly, this should be cpuclk/3. When
removing the clocks {} container above, please also take care of
it.
You understood correctly
You can do
cpuclk: cpu-clock {
compatible = "fixed-clock";
#clock-cells = <0>;
clock-frequency = <1200000000>; /* <- put correct freq here */
};
sysclk: system-clock {
compatible = "fixed-factor-clock";
#clock-cells = <0>;
clocks = <&cpuclk>;
clock-multi = <1>;
clock-div = <3>;
};
Hopefully, we'll have proper clock drivers soon so we can just replace
referenced "fixed-*" clocks.
I'm working on that, do you have some code that you can share right now ?
No, nothing specific. You can have a look at drivers/clk/mvebu/ and see
how we deal with it on mvebu. For now, you can stick with bg2q and I'll
see how we extend that drivers for bg2/bg2cd then.
BTW: We really enjoy having a mvebu subfolder in drivers/clk as it makes
things easier. If you prepare any clk drivers for berlin, I'd suggest to
put them in drivers/clk/berlin from the beginning.
