[PATCH v2 29/29] [RFC] arm64: dts: renesas: r8a779m5: Add Cortex-A57 2 GHz opp
From: Geert Uytterhoeven <geert+renesas@glider.be>
Date: 2021-08-12 11:24:35
Also in:
linux-arm-kernel, linux-renesas-soc
Subsystem:
arm/risc-v/renesas architecture, the rest · Maintainers:
Geert Uytterhoeven, Magnus Damm, Linus Torvalds
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.
