Subject: [PATCH v1 -next 2/3] cpufreq: Move CPPC configs to common Kconfig and add RISC-V
Date: Thu,  8 Feb 2024 09:14:13 +0530	[thread overview]
Message-ID: <20240208034414.22579-3-sunilvl@ventanamicro.com> (raw)
In-Reply-To: <20240208034414.22579-1-sunilvl@ventanamicro.com>

CPPC related config options are currently defined only in ARM specific
file. However, they are required for RISC-V as well. Instead of creating
a new Kconfig.riscv file and duplicating them, move them to the common
Kconfig file and enable RISC-V too.
