[PATCH v2 29/29] [RFC] arm64: dts: renesas: r8a779m5: Add Cortex-A57 2 GHz opp

[Geert Uytterhoeven]

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.

v2:
  - Change 2 GHz opp from 1020000 µV to 960000 µV, as per informal
    communication.
