Subject: [PATCH 1/2] dt-bindings: cpufreq: Add big CPU supply
Date: Fri, 29 Dec 2023 18:28:39 -0300 [thread overview]
Message-ID: <20231229212853.277334-1-nfraprado@collabora.com> (raw)
The performance-controller hardware block on MediaTek SoCs is
responsible for controlling the frequency of the CPUs. As such, it needs
any CPU regulator to have been configured prior to initializing. Add a
phandle in the binding so this dependency can be described.
