[Patch v3 0/4] Tegra234 cpufreq driver support

[Sumit Gupta <sumitg@nvidia.com>]

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
