Subject: [PATCH v3 11/13] arm64: dts: apple: t8103, t8112, t60xx: add hwmon SMC subdevice
Date: Tue, 07 Oct 2025 21:16:52 +1000 [thread overview]
Message-ID: <20251007-macsmc-subdevs-v3-11-d7d3bfd7ae02@gmail.com> (raw)
In-Reply-To: <20251007-macsmc-subdevs-v3-0-d7d3bfd7ae02@gmail.com>
Apple's System Management Controller integrates numerous sensors
that can be exposed via hwmon. Add the subdevice and compatible
in preparation for the sensors that need to be described
for each device.
