This patchset adds driver support for Tegra234 cpufreq. Also, added soc data and ops to support multiple SoC's and variants which have similar logic to {get|set} cpu frequency as Tegra194 in the same driver. From cpufreq point, main difference between Tegra194 and Tegra234 are: 1) Tegra234 uses MMIO for frequency requests and not sysreg like T194. 2) MPIDR affinity info in Tegra234 is different from Tegra194. 3) Register bits of pllp_clk_count and core_clk_count are swapped. So, added ops hooks for Tegra234.
--- v2 -> v3: - used CPU COMPLEX CLUSTER name in binding document. - reordered the patches.
v1 -> v2: - added nvidia,tegra-ccplex-cluster.yaml binding doc - changed compatible check to 'soc->actmon_cntr_base' field of soc data
