[PATCH/RFC 14/14] arm64: dts: renesas: r8a779m3: Add Cortex-A57 2 GHz opp

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
