Subject: [PATCH v9 00/15] CPU scaling support for msm8996

[v9]
 * Addressed comments from Viresh and Russel about the error handling

[v8]
 * Reordered the patch series into 4 groups
 * Addressed comments from Amit about the comments and commit messages
 * Addressed comments from Amit and Viresh about the resourses deallocation

[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

The series contains 4 groups of patches, which can be merged in the chain order,
while each group depends on all the previous groups.
(However, Only SOC, or SOC and Clocks, or SOC and Clocks and Cpufreq will work)  

SOC (1/15):
Extracts the kryo l2 accessors driver from the QCOM PMU driver

Clocks (2/15-9/15):
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.

Cpufreq (10/15-12/15):
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.

Regulators (13/15-15/15):
Added SAW regulator support to the SPMI regulator driver. The SAW regulators
will be controlled through special CPU registers instead of direct
SPMI accesses.

Ilia Lin (13):
  soc: qcom: Separate kryo l2 accessors from PMU driver
  clk: Use devm_ in the register fixed factor clock
  clk: qcom: Add CPU clock driver for msm8996
  dt-bindings: clk: qcom: Add bindings for CPU clock for msm8996
  clk: qcom: cpu-8996: Add support to switch below 600Mhz
  clk: qcom: Add ACD path to CPU clock driver for msm8996
  dt: qcom: Add opp and thermal to the msm8996
  cpufreq: Add Kryo CPU scaling driver
  dt-bindings: cpufreq: Document operating-points-v2-kryo-cpu
  dt: qcom: Add qcom-cpufreq-kryo driver configuration
  regulator: qcom_spmi: Add support for SAW
  dt-bindings: qcom_spmi: Document SAW support
  dt: qcom: Add SAW regulator for 8x96 CPUs

Rajendra Nayak (2):
  clk: qcom: Make clk_alpha_pll_configure available to modules
  clk: qcom: cpu-8996: Add support to switch to alternate PLL
