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
