Subject: [PATCH v2 3/3] arm64: dts: allwinner: h6: orangepi: Enable CPU frequency scaling
Date: Sun, 15 Nov 2026 14:22:14 +0100	[thread overview]
Message-ID: <20261115132215.289236-4-jernej.skrabec@gmail.com> (raw)
In-Reply-To: <20261115132215.289236-1-jernej.skrabec@gmail.com>

The Orange Pi One Plus and Lite2 lack the CPU OPP table and CPU supply,
so the CPU never scales its frequency. Add both, like on Orange Pi 3.
OPPs above the regulator constraints stay unused.
