Subject: [PATCH 0/3] Platform/RasberryPi: Thermal zone
Date: Thu, 13 Aug 2020 18:00:53 -0500 [thread overview]
Message-ID: <20200813230056.40526-1-jeremy.linton@arm.com> (raw)
This set creates a basic thermal zone, which reads the
SOC temp via a direct register read in AML. It also
adds an active cooling policy using a GPIO pin for fan
control that can optionally be enabled/disabled by the
user from the BDS.
With the fan enabled it should be possible to see the
soc temp like:
# sensors
acpitz-acpi-0
Adapter: ACPI interface
temp1: +57.6C (crit = +90.0C)
and the fan state may be read/cycled with:
/sys/bus/acpi/devices/PNP0C06:00/PNP0C0B:00/physical_node/thermal_cooling/cur_state
