Subject: [PATCH 3/3] arm64, topology: enable use of init_cpu_capacity_cppc()
Date: Fri, 14 May 2021 10:53:39 +0100	[thread overview]
Message-ID: <20210514095339.12979-4-ionela.voinescu@arm.com> (raw)
In-Reply-To: <20210514095339.12979-1-ionela.voinescu@arm.com>

Now that the arch topology driver provides a method of setting CPU
capacity values based on information on highest performance from CPPC,
use this functionality on arm64 platforms.
