Subject: [PATCH v2 3/4] arm64: dts: rockchip: Add OPP data for CPU cores on RK3588
Date: Tue, 30 Jan 2024 22:21:15 +0400 [thread overview]
Message-ID: <20240130-rk-dts-additions-v2-3-c6222c4c78df@gmail.com> (raw)
In-Reply-To: <20240130-rk-dts-additions-v2-0-c6222c4c78df@gmail.com>
By default the CPUs on RK3588 start up in a conservative performance
mode. Add frequency and voltage mappings to the device tree to enable
dynamic scaling via cpufreq
