Subject: [PATCH 6/8] ARM: mstar: Add OPP table for infinity
Date: Tue, 23 Feb 2021 15:18:28 +0900	[thread overview]
Message-ID: <20210223061830.1913700-7-daniel@0x0f.com> (raw)
In-Reply-To: <20210223061830.1913700-1-daniel@0x0f.com>

Add an OPP table for the inifinity chips so
that cpu frequency scaling can happen.
