thermal/drivers/qcom-spmi-temp-alarm: Enable stage 2 shutdown when required

2025-08-20T16:40:59+00:00

[ Upstream commit f8e157ff2df46ddabd930815d196895976227831 ]

Certain TEMP_ALARM GEN2 PMIC peripherals need over-temperature stage 2
automatic PMIC partial shutdown. This will ensure that in the event of
reaching the hotter stage 3 over-temperature threshold, repeated faults
will be avoided during the automatic PMIC hardware full shutdown.
Modify the stage 2 shutdown control logic to ensure that stage 2
shutdown is enabled on all affected PMICs. Read the digital major
and minor revision registers to identify these PMICs.

Pull thermal control updates from Rafael Wysocki:
 "These add support for a new feature, Platform Temperature Control
  (PTC), to the Intel int340x thermal driver, add support for the Airoha
  EN7581 thermal sensor and the IPQ5018 platform, fix up the ACPI
  thermal zones handling, fix other assorted issues and clean up code

  Specifics:

   - Add Platform Temperature Control (PTC) support to the Intel int340x
     thermal driver (Srinivas Pandruvada)

   - Make the Hisilicon thermal driver compile by default when ARCH_HISI
     is set (Krzysztof Kozlowski)

   - Clean up printk() format by using %pC instead of %pCn in the
     bcm2835 thermal driver (Luca Ceresoli)

   - Fix variable name coding style in the AmLogic thermal driver
     (Enrique Isidoro Vazquez Ramos)

   - Fix missing debugfs entry removal on failure by using the devm_
     variant in the LVTS thermal driver (AngeloGioacchino Del Regno)

   - Remove the unused lvts_debugfs_exit() function as the devm_ variant
     introduced before takes care of removing the debugfs entry in the
     LVTS driver (Arnd Bergmann)

   - Add the Airoha EN7581 thermal sensor support along with its DT
     bindings (Christian Marangi)

   - Add ipq5018 compatible string DT binding, cleanup and add its
     suppot to the QCom Tsens thermal driver (Sricharan Ramabadhran,
     George Moussalem)

   - Fix comments typos in the Airoha driver (Christian Marangi, Colin
     Ian King)

   - Address a sparse warning by making a local variable static in the
     QCom thermal driver (George Moussalem)

   - Fix the usage of the _SCP control method in the driver for ACPI
     thermal zones (Armin Wolf)"

thermal: Switch to irq_domain_create_linear()

2025-05-16T19:06:11+00:00

irq_domain_add_linear() is going away as being obsolete now. Switch to
the preferred irq_domain_create_linear(). That differs in the first
parameter: It takes more generic struct fwnode_handle instead of struct
device_node. Therefore, of_fwnode_handle() is added around the
parameter.

Note some of the users can likely use dev->fwnode directly instead of
indirect of_fwnode_handle(dev->of_node). But dev->fwnode is not
guaranteed to be set for all, so this has to be investigated on case to
case basis (by people who can actually test with the HW).

thermal/drivers/qcom/tsens: Add support for IPQ5018 tsens

2025-05-16T10:50:01+00:00

IPQ5018 has tsens IP V1.0, 5 sensors of which 4 are in use and 1
interrupt. The IP does not have a RPM, hence use init routine for
tsens v1.0 without RPM which does not early enable.

thermal/drivers/qcom/tsens: Add support for tsens v1 without RPM

2025-05-16T10:50:01+00:00

Adding generic support for SoCs with tsens v1.0 IP with no RPM.
Due to lack of RPM, tsens has to be reset and enabled in the driver
init. SoCs can have support for more sensors than those which will
actually be enabled. As such, init will only enable those explicitly
added to the hw_ids array.

thermal/drivers/qcom/tsens: Update conditions to strictly evaluate for IP v2+

2025-05-16T10:50:01+00:00

TSENS v2.0+ leverage features not available to prior versions such as
updated interrupts init routine, masked interrupts, and watchdog.
Currently, the checks in place evaluate whether the IP version is greater
than v1 which invalidates when updates to v1 or v1 minor versions are
implemented. As such, update the conditional statements to strictly
evaluate whether the version is greater than or equal to v2 (inclusive).

thermal/drivers/tsens: Add TSENS enable and calibration support for V2

2025-03-25T19:52:03+00:00

SoCs without RPM need to enable sensors and calibrate them from the kernel.
The IPQ5332 and IPQ5424 use the tsens v2.3.3 IP and do not have RPM.
Therefore, add a new calibration function for V2, as the tsens.c calib
function only supports V1. Also add new feature_config, ops and data for
IPQ5332, IPQ5424.

Although the TSENS IP supports 16 sensors, not all are used. The hw_id
is used to enable the relevant sensors.
