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-spmi-adc-tm5: Drop IIO_VAL_INT check in adc_tm5_get_temp

2026-07-27T14:15:06+00:00

Commit bb21ee31f575 ("iio: Fix iio_multiply_value use in iio_read_channel_processed_scale") fixed the iio_read_channel_processed_scale to return 0 on success instead of IIO_VAL_INT (1). The existing check in adc_tm5_get_temp() treated a successful return as an error because it expected IIO_VAL_INT. Drop the redundant `ret != IIO_VAL_INT` condition and rely solely on the negative error check.

iio: inkern: Use namespaced exports

2026-07-05T00:37:19+00:00

Use namespaced exports for IIO consumer API functions. This will make it easier to manage the IIO export surface. Consumer drivers will only be provided access to a specific set of functions, thereby restricting usage of internal IIO functions by other parts of the kernel. This change cannot be split into several parts without breaking bisectability, thus all of the affected drivers are modified at once.

thermal/drivers/qcom/tsens: Disable wakeup interrupt setup on automotive targets

2026-06-03T07:13:04+00:00

Add a no_irq_wake flag to struct tsens_plat_data to allow platforms to control whether TSENS interrupts should be configured as wakeup sources. Create a new data_automotive structure and add compatible strings for automotive TSENS variants (SA8775P, SA8255P) with wakeup interrupts disabled. Automotive platforms can enter a low-power parking suspend state where the application processors and thermal mitigation paths are not active. In this state, waking the system due to TSENS threshold interrupts does not enable useful thermal action, but it does repeatedly break suspend residency and increase battery drain. Allow these automotive variants to keep TSENS monitoring enabled during normal runtime while opting out of TSENS wakeup interrupts during suspend, so the system can remain in low power until ignition/resume.
