thermal/drivers/qcom: add support for PMIC5 Gen3 ADC thermal monitoring

2026-08-07T15:18:45+00:00

Add support for ADC_TM part of PMIC5 Gen3 in an auxiliary driver under the Gen3 ADC driver. Its functionality is similar to that of PMIC5 Gen2 ADC_TM, which implements the threshold setting and interrupt generating functions, used to support thermal trip points. In Gen3 ADC, the register interface is implemented on one or more SDAM (Shared Direct Access Memory) peripherals instead of dedicated ADC peripherals. Each ADC SDAM has eight channels which can be configured for either immediate reads (main ADC driver's functionality) or ADC_TM reads. By convention, the first channel of the first ADC SDAM is reserved for all immediate reads and remaining channels across all SDAMs are used for ADC_TM functionality. On the first SDAM, the interrupt line and configuration registers are shared between the main ADC and auxiliary ADC_TM drivers. Access to the registers is protected through a mutex shared between the drivers. The ADC_TM driver accesses this mutex and some other functions shared from the main driver (like adc5_gen3_get_scaled_reading() for immediate channel reads in the .get_temp() callback) through APIs exported into a shared namespace.

thermal/drivers/qcom: Add support for Qualcomm MBG thermal monitoring

2026-08-07T15:18:34+00:00

Add a driver for the Qualcomm MBG (Master Bandgap) thermal monitoring device. It monitors PMIC die temperature in hardware and raises an interrupt when a programmed threshold is crossed. MBG hardware supports two upper-threshold levels. Currently, only the level-1 threshold is supported by the driver. Temperature is read from the associated ADC channel, and when a level-1 upper-threshold violation occurs, the hardware generates an interrupt over SPMI. The driver notifies the thermal framework accordingly.

thermal/drivers/qcom: Add support for LMh driver

2021-08-18T07:32:25+00:00

Driver enabling various pieces of Limits Management Hardware(LMh) for cpu cluster0 and cpu cluster1 namely kick starting monitoring of temperature, current, battery current violations, enabling reliability algorithm and setting up various temperature limits. The following has been explained in the cover letter. I am including this here so that this remains in the commit message as well. LMh is a hardware infrastructure on some Qualcomm SoCs that can enforce temperature and current limits as programmed by software for certain IPs like CPU. On many newer LMh is configured by firmware/TZ and no programming is needed from the kernel side. But on certain SoCs like sdm845 the firmware does not do a complete programming of the h/w. On such soc's kernel software has to explicitly set up the temperature limits and turn on various monitoring and enforcing algorithms on the hardware.

thermal: qcom: add support for adc-tm5 PMIC thermal monitor

2021-02-15T20:28:53+00:00

Add support for Thermal Monitoring part of PMIC5. This part is closely coupled with ADC, using it's channels directly. ADC-TM support generating interrupts on ADC value crossing low or high voltage bounds, which is used to support thermal trip points.

drivers: thermal: tsens: Merge tsens-common.c into tsens.c

2020-05-22T16:53:04+00:00

tsens-common.c has outlived its usefuless. It was created expecting lots of custom routines per version of the TSENS IP. We haven't needed those, there is now only data in the version-specific files. Merge the code for tsens-common.c into tsens.c. As a result, - Remove any unnecessary forward declarations in tsens.h. - Add a Linaro copyright to tsens.c. - Fixup the Makefile to remove tsens-common.c. - Where it made sense, fix some 80-column alignments in the tsens-common.c code being copied over. There is no functional change with this patch.

This cleans up the directory a bit allowing just one place to look for thermal related drivers for QCOM platforms instead of being scattered in the root directory and the qcom/ subdirectory.
