Subject: [PATCH v2 29/29] [RFC] arm64: dts: renesas: r8a779m5: Add Cortex-A57 2 GHz opp
Date: Thu, 12 Aug 2021 13:24:19 +0200 [thread overview]
Message-ID: <bbfb67c95e0c2bc3312bf46b7a28b6baa452786a.1628766192.git.geert+renesas@glider.be> (raw)
In-Reply-To: <cover.1628766192.git.geert+renesas@glider.be>
Add a preliminary operating point for running the Cortex-A57 CPU cores
on R-Car M3Ne-2G at 2 GHz.
The opp-microvolt value depends on a future update of the Electrical
Characteristics for R-Car M3Ne-2G.
Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be>
---
v2:
- Change 2 GHz opp from 1020000 µV to 960000 µV, as per informal
communication.
