Subject: [PATCH v2 0/3] Support for autonomous selection in cppc_cpufreq

Add sysfs interfaces for CPPC autonomous selection in the cppc_cpufreq
driver.

The patch series is organized in two parts:

 - patch 1 refactor out the general CPPC register get and set functions
   in cppc_acpi.c

 - patches 2-3 expose sysfs files for users to control CPPC autonomous
   selection when supported

Change since v1:
 - fix some incorrect placeholder
 - change kstrtoul to kstrtobool in store_auto_select

  ACPI: CPPC: Refactor register get and set ABIs
  ACPI: CPPC: Add autonomous selection ABIs
  cpufreq: CPPC: Support for autonomous selection in cppc_cpufreq
