Pull more thermal control updates from Rafael Wysocki:
 "This mostly consists of assorted updates of thermal drivers, including
  new hardware support (Airoha AN7583, Qualcomm Master BandGap thermal
  monitor, QCom PMIC5 Gen3 ADC), but it also includes two reverts of
  recent cosmetic thermal core updates that went against driver core
  plans to eliminate class_create():

   - Fix missing bitfield include headers in Armada and QCom SPM BMG
     drivers (Daniel Lezcano)

   - Fix missed file when manually applying a change after a conflict
     resolution for the QCom SPMI ADC TM5 Gen3 (Daniel Lezcano)

   - Move thermal_zone_device_enable() to the right place in order to
     prevent calling it if the thermal zone registration failed (Dan
     Carpenter)

   - Improve bitfield manipulations on Armada (Bryan B. Lima)

   - Remove unneeded 'fast_io' on Sun8i and Armada (Wolfram Sang)

   - Fix wrong boundary when clamping the low values in the set_trips()
     callback and fix wrong mask when setting the temperature interval
     on Airoha (Christian Marangi)

   - Make use of the regmap API to support Airoha AN7583 (Christian
     Marangi)

   - Fix adc_tm5_get_temp() return check value on the QCom SPMI ADC
     sensor (Rakesh Kota)

   - Fix unbalanced clock enablement when the resume fails on the iMX
     driver (Can Peng)

   - Add Qualcomm Master BandGap thermal monitor support (Satya Priya
     Kakitapalli)

   - Add Maili Temperature bindings compatible (Haritha S K)

   - Add a devm action to clean hardware interrupts, sampling, and
     control registers on Spacemit K1 (Pei Xiao)

   - Fix trivial typo in a thermal OF code comment (Marek Vasut)

   - Remove unnecessary print on Qcom SPMI ADC driver when a call to
     devm_request_threaded_irq() fails as this one already prints a
     message (Jishnu Prakash)

   - Add support for QCom PMIC5 Gen3 ADC by using auxiliary driver and
     shared interrupt with the IIO driver (Jishnu Prakash)

   - Make resets optional on MT8196 and add the corresponding property
     in the DT bindings (AngeloGioacchino Del Regno)

   - Fix clock staying enabled on failing resume operation on Qoriq (Can
     Peng)

   - Fix wrong closing brace position in thermal library header (Andreas
     Haufler)

   - Fix low and high trip point validation by moving the check after
     the clamp on the spacemit driver (surendra)

   - Remove redundant error messages on IRQ request failure (Pan Chuang)

   - Add IIO_CONSUMER namespace import to the qcom-spmi-mbg-tm thermal
     driver to avoid modpost warnings that would appear after merging
     the iio tree against the thermal updates (Nathan Chancellor)

   - Revert two recent cosmetic updates of the thermal core conflicting
     with driver core plans to eliminate class_create() (Rafael
     Wysocki)"

+title: Qualcomm's SPMI PMIC MBG Thermal Monitoring
+
+maintainers:
+ - Jishnu Prakash <[email protected]>
+ - Kamal Wadhwa <[email protected]>
+
+description:
+ Qualcomm's MBG(Master Bandgap) temperature alarm monitors the die
+ temperature and generates an interrupt if the PMIC die temperature is
+ over a set of programmable temperature thresholds. It allows monitoring
+ for both hot and cold, LVL1 and LVL2 thresholds, which makes it different
+ from the existing temp alarm peripheral. The interrupt comes over SPMI
+ and the MBG's fault status register gives details to understand whether
+ it is a hot/cold and LVL1/LVL2 violation.
