Subject: [PATCH v7 00/14] CPU scaling support for msm8996

[v7]
 * Addressed comments from Viresh about resourses deallocation
   and DT compatible

[v6]
 * Addressed comments from Viresh about:
 ** Comments style
 ** Kconfig bool instead of tristate
 ** DT and documentation style
 ** Resourses deallocation on an error
 ** Typos

[v5]
 * Rebased
 * Addressed comments from Bjorn about SPDX style,
   functions and parameters naming
 * Addressed comments from Viresh DT properties and style, comments style,
   resourses deallocation, documentation placement
 * Addressed comments from Sricharan about unnessesary include
 * Addressed comments from Nicolas
 * Addressed comments from Rob about the commit messages and acks
 * Addressed comments from Mark

[v4]
 * Adressed all comments from Stephen
 * Added CPU regulator support
 * Added qcom-cpufreq-kryo driver

[v3]
 * Rebased on top of the latest PLL driver changes
 * Addressed comment from Rob Herring for bindings

[v2]
 * Addressed comments from Rob Herring for bindings
 * Addressed comments from Mark Rutland for memory barrier
 * Addressed comments from Julien Thierry for clock reenabling condition
 * Tuned the HW configuration for clock frequencies below 600MHz

Clocks:
This series adds support for the CPU clocks on msm8996 devices.
The driver uses the existing PLL drivers and is required to control
the CPU frequency scaling on the MSM8996.

Regulators:
Added SAW regulator support to the SPMI regulator driver. The SAW regulators
will be controlled through special CPU registers instead of direct
SPMI accesses.

Cpufreq:
The qcom-cpufreq-kryo driver is aimed to support different SOC versions.
The driver reads eFuse information and chooses the required OPP subset
by passing the OPP supported-hw parameter.
