Subject: [PATCH v2 7/9] ARM: mstar: Add OPP table for infinity3
Date: Sun, 2 Jan 2022 17:57:28 +0100 [thread overview]
Message-ID: <20220102165730.50190-8-romain.perier@gmail.com> (raw)
In-Reply-To: <20220102165730.50190-1-romain.perier@gmail.com>
From: Daniel Palmer <daniel@0x0f•com>
The infinity3 has a slightly higher max frequency
compared to the infinity so extend the OPP table.
