In the case of Mediatek SoC, the intermediate frequency might not be one entry
of OPP table. To elaborate, the source clock node of the CPUs/Cluster on
Mediatek SoC is a mux. The mux has several PLLs as parents. When we are
doing CPU frequency scaling, the mux should re-parent to another stable PLL,
wait until the original parent PLL become stable, and then switch back to the
original parent. In this case, we could but we might not want the intermediate
frequency as part of OPP table. Therefore I save intermediate_freq instead of
intermediate frequency index in the cpufreq_dt_platform_datat struct.

Hmm, I remember that discussion. Okay leave it as is.

Okay.

BTW, is this case that intermediate frequency is not necessarily be one entry
of OPP table supported in the OPPv2 bindings?

Not yet, but will add a property for that.

Thanks for taking this case into consideration.
