As Ionela pointed out earlier in the thread, the cpufreq driver for Juno was not acceptable for mainline because it used platform specific code. When it was converted to cpufreq-dt, the static power was left behind because it can't be represented in device tree. This is because there isn't a function that works for every SoC, different process nodes (among other things) will need different functions. So it can't be just a bunch of coefficients in DT, we need a function. Hence the callback. In a nutshell, mainline does not want platform specific code, but we haven't figured out how to calculate static power without platform specific code. Cheers, Javi
