Message

This series is a new tentative for adding MSM8996 CPU scaling support
based on the previous Ilia's series, with some of the latest comments
addressed.

This series has been tested with dragonboard-820c and cpufreq-bench.
The CPU opps are limited to maximum nominal frequencies (no turbo).

v2:
    - Converted dt bindings to YAML
    - Various fixes from Stephen inputs
    - Removed useless wmb barrier, MODULE_ALIAS
    - Use helpers like struct_size() and devm_platform_ioremap_resource()
    - Coding style fixes + comments
    - Kconfig: remove useless depends
    - Added Co-developed-by tag

v3:
    - Added Ilia and Rajendra s-o-b and contribution description

v4:
    - Rebasing on master
    - Removing obsolete cooling-min-level and cooling-max-level props
    - Align cpu trip nodes names with other boards
    - Fix trip types to passive for cpufreq

v5:
    - Fix reported 0-DAY CI issues, read_cpuid_mpidr usage requires ARM64 conf
    - Fix cpu_crit node labels
    - Dedicated patch for speedbin node name change
    - Added patch description for dtsi patch

v6:
    - Add Acked-by Will tag to l2 kryo accessors patch
    - Fix msm8996,apcc dt binding file (errors reported by dt_binding_check)

Ilia Lin (2):
  soc: qcom: Separate kryo l2 accessors from PMU driver
  dt-bindings: clk: qcom: Add bindings for CPU clock for msm8996

Loic Poulain (3):
  clk: qcom: Add CPU clock driver for msm8996
  arch: arm64: dts: msm8996: Rename speedbin node
  arch: arm64: dts: msm8996: Add CPU opps and thermal

I got this one.

I've already applied v5. Please send incremental patches to fix the
dt_binding_check problem.
