Subject: [PATCH 5/7] intel-speed-select: Implement CascadeLake-N help and command functions structures
Date:   Thu, 26 Sep 2019 08:54:59 -0400
Message-Id: <20190926125501.1616-6-prarit@redhat.com>

Precedence: bulk

CascadeLake-N only supports SST-BF and needs some of the perf-profile
commands, and the base-freq commands.

Add help functions, and create an empty command structures (the functions
will be implemented later in this patchset).  Call these functions
when running on CascadeLake-N.
