| |
RK3899 has one cluster with 4 small cores, and another one with 2 big cores, with cores in different clusters having different OPPs and thus needing separate set of tunables. Let's enable this via "have_governor_per_policy" platform data.

v2 changes: commit message updated.
Not tested, but we had a patch unconditionally enabling CPUFREQ_HAVE_GOVERNOR_PER_POLICY flag in tree we used to ship devices based on RK3399 platform.
