2021-02-15thermal: qcom: add support for adc-tm5 PMIC thermal monitorDmitry Baryshkov1-0/+1
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.

2020-05-22drivers: thermal: tsens: Merge tsens-common.c into tsens.cAmit Kucheria1-2/+2
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.

2019-05-14drivers: thermal: tsens: Add generic support for TSENS v1 IPAmit Kucheria1-1/+3
qcs404 has a single TSENS IP block with 10 sensors. It uses version 1.4 of the TSENS IP, functionality for which is encapsulated inside the qcom,tsens-v1 compatible. Signed-off-by: Amit Kucheria <amit.kucheria@linaro.org> Signed-off-by: Eduardo Valentin <edubezval@gmail.com>

8974 and 8916 have the same version of the TSENS IP. Merge the files to allow for better code reuse. Signed-off-by: Amit Kucheria <amit.kucheria@linaro.org> Signed-off-by: Eduardo Valentin <edubezval@gmail.com>

8916 and 8974 use v0.1.0 of the TSENS IP. Rename tsens-8916 to prepare it for merging with tsens-8974 in a later commit. Signed-off-by: Amit Kucheria <amit.kucheria@linaro.org> Signed-off-by: Eduardo Valentin <edubezval@gmail.com>
2018-12-07drivers: thermal: Move QCOM_SPMI_TEMP_ALARM into the qcom subdirAmit Kucheria1-0/+1
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. Compile-tested with ARCH=arm64 defconfig and the driver explicitly enabled with menuconfig.

2018-07-27thermal: tsens: Rename tsens-8996 to tsens-v2 for reuseAmit Kucheria1-1/+1
The TSENS block inside the 8996 is internally classified as version 2 of the IP. Several other SoC families use this block and can share this code. We rename get_temp() to reflect that it can be used across the v2 family.

2016-09-27thermal: qcom: tsens-8996: Add support for 8996 family of SoCsRajendra Nayak1-1/+1
The TSENS controller in 8996 family of SoCs is capable of converting the ADC code outputs to real temperature values (in decidegree Celsius). It can also be programmed to provide raw ADC code, but the secure software on 8996 programs it to provide real temperatures and also does the needed calibrations. We check the valid bit to ensure valid data is read by the AHB master. And the spec recommends the below algorithm to read data 3 consecutive times, which takes care of the worst case delay taken to propagate the updated data to the register.

2016-09-27thermal: qcom: tsens-8960: Add support for 8960 family of SoCsRajendra Nayak1-1/+1
8960 family of SoCs have the TSENS device as part of GCC, hence the driver probes the virtual child device created by GCC and uses the parent to extract all DT properties and reuses the GCC regmap. Also GCC/TSENS are part of a domain thats not always ON. Hence add .suspend and .resume hooks to save and restore some of the inited register context. Also 8960 family have some of the TSENS init sequence thats required to be done by the HLOS driver (some later versions of TSENS do not export these registers to non-secure world, and hence need these initializations to be done by secure bootloaders) 8660 from the same family has just one sensor and hence some register offset/layout differences which need special handling in the driver. Based on the original code from Siddartha Mohanadoss, Stephen Boyd and Narendran Rajan.

2016-09-27thermal: qcom: tsens: Add a skeletal TSENS driversRajendra Nayak1-0/+2
TSENS is Qualcomms' thermal temperature sensor device. It supports reading temperatures from multiple thermal sensors present on various QCOM SoCs. Calibration data is generally read from a non-volatile memory (eeprom) device. Add a skeleton driver with all the necessary abstractions so a variety of qcom device families which support TSENS can add driver extensions. Also add the required device tree bindings which can be used to describe the TSENS device in DT.
