Subject: [PATCH/RFC 14/14] arm64: dts: renesas: r8a779m3: Add Cortex-A57 2 GHz opp
Date: Thu, 10 Jun 2021 11:37:27 +0200	[thread overview]
Message-ID: <6dbc16b1345913cb42d8824d1c0f7f5be7645cf9.1623315732.git.geert+renesas@glider.be> (raw)
In-Reply-To: <cover.1623315732.git.geert+renesas@glider.be>

Add a preliminary operating point for running the Cortex-A57 CPU cores
on R-Car M3e-2G at 2 GHz.

The opp-microvolt value depends on a future update of the Electrical
Characteristics for R-Car M3e-2G.
