Cover letter [Patch v3 0/2] Improvements to the Tegra CPUFREQ driver
This patch set adds below improvements to the Tegra194 CPUFREQ driver. They are applicable to all the Tegra SoC's supported by the driver.
1) Patch 1: Avoid making SMP call on every frequency request to reduce the time for frequency set and get calls.
2) Patch 2: Use reference clock count based loop instead of udelay() to improve the accuracy of re-generated CPU frequency.
The patches are not related but have minor conflict. So, need to be applied in order of patch numbers. If 'Patch 2' is to be applied first then will rebase that and send separately.

v1[2] -> v3:
- Patch 1: used sizeof(*data->cpu_data) in devm_kcalloc().
v1[1] -> v2:
- Patch 1: added new patch.
- Patch 2: changed subject and patch order.
