Subject: [PATCH v2 0/4] Platform/RasberryPi: Thermal zone
Date: Wed, 19 Aug 2020 23:42:13 -0500	[thread overview]
Message-ID: <20200820044217.39839-1-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 on either
GPIO18 (commercial fan shim board) or GPIO19 by the
user from the BDS.

it should now be possible when booted in ACPI mode to:

# sensors
acpitz-acpi-0
Adapter: ACPI interface
temp1:        +57.6C  (crit = +90.0C)

and the fan state, if enabled may be read with:

/sys/bus/acpi/devices/PNP0C06:00/PNP0C0B:00/physical_node/thermal_cooling/cur_state

while the kernel will automatically cycle the fan if the SoC
temp exceeds 60C.


v1->v2:
  Add choice of GPIO pins to the BDS menu
  Correct whitespace/etc issues from v1 review
  Add an additional cleanup patch for contextual whitespace issues

  Platform/RaspberryPi4: Add a basic thermal zone
  Platform/RaspberryPi4: Create ACPI fan object
  Platform/RaspberryPi: Add entry for user fan control
  Platform/RaspberryPi: Trivial whitespace cleanup
