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 Lifeng Zheng (3): ACPI: CPPC: Refactor register get and set ABIs ACPI: CPPC: Add autonomous selection ABIs cpufreq: CPPC: Support for autonomous selection in cppc_cpufreq .../ABI/testing/sysfs-devices-system-cpu | 54 ++++ drivers/acpi/cppc_acpi.c | 235 +++++++++--------- drivers/cpufreq/cppc_cpufreq.c | 138 ++++++++++ include/acpi/cppc_acpi.h | 20 ++ 4 files changed, 328 insertions(+), 119 deletions(-)
