Merge patch series "RISC-V: ACPI: Enable CPPC based cpufreq support"
Sunil V L <sunilvl@ventanamicro.com> says:
This series enables the support for "Collaborative Processor Performance
Control (CPPC) on ACPI based RISC-V platforms. It depends on the
encoding of CPPC registers as defined in RISC-V FFH spec [2].
CPPC is described in the ACPI spec [1]. RISC-V FFH spec required to
enable this, is available at [2].
