Subject: [PATCH 1/5] dt-bindings: mfd: syscon: Add mt8196 fdvfs syscons
Date: Fri, 11 Jul 2025 16:57:33 +0200 [thread overview]
Message-ID: <20250711-mt8196-cpufreq-v1-1-e1b0a3b4ac61@collabora.com> (raw)
In-Reply-To: <20250711-mt8196-cpufreq-v1-0-e1b0a3b4ac61@collabora.com>
The MT8196 SoC uses two syscon ranges for CPU DVFS that are separate
from each other. One, mt8196-fdvfs-config, is used to check for a magic
number at that memory address to verify that fdvfs should be used. The
other, mt8196-fdvfs, is used to configure the desired frequency for the
DVFS controller for each CPU core.
