Currently the check of chip->channels[i].channel is against an the
uninitialized variable channels_available. I believe the variable
channels_available needs to be fetched first by the call to adc_tm5_read
before the channels check. Fix the issue swapping the order of the
channels check loop with the call to adc_tm5_read.

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.

Currently driver is suppressing the negative temperature
readings from the vadc. Consumers of the thermal zones need
to read the negative temperature too. Don't suppress the
readings.

The TSENS integrated on MSM8939 is a v0_1 device with 10 sensors. Different from its predecessor MSM8916, where 'calib_sel' bits sit in separate qfprom word, MSM8939 has 'cailb' and 'calib_sel' bits mixed and spread on discrete offsets. That's why all qfprom bits are read as one go and later mapped to calibration data for MSM8939.

After merging tsens-common.c into tsens.c, we can now mark some functions static so they don't need any prototype declarations. This fixes the following issue reported by lkp. >> drivers/thermal/qcom/tsens.c:385:13: warning: no previous prototype for 'tsens_critical_irq_thread' [-Wmissing-prototypes] 385 | irqreturn_t tsens_critical_irq_thread(int irq, void *data) | ^~~~~~~~~~~~~~~~~~~~~~~~~ >> drivers/thermal/qcom/tsens.c:455:13: warning: no previous prototype for 'tsens_irq_thread' [-Wmissing-prototypes] 455 | irqreturn_t tsens_irq_thread(int irq, void *data) | ^~~~~~~~~~~~~~~~ >> drivers/thermal/qcom/tsens.c:523:5: warning: no previous prototype for 'tsens_set_trips' [-Wmissing-prototypes] 523 | int tsens_set_trips(void *_sensor, int low, int high) | ^~~~~~~~~~~~~~~ >> drivers/thermal/qcom/tsens.c:560:5: warning: no previous prototype for 'tsens_enable_irq' [-Wmissing-prototypes] 560 | int tsens_enable_irq(struct tsens_priv *priv) | ^~~~~~~~~~~~~~~~ >> drivers/thermal/qcom/tsens.c:573:6: warning: no previous prototype for 'tsens_disable_irq' [-Wmissing-prototypes] 573 | void tsens_disable_irq(struct tsens_priv *priv) | ^~~~~~~~~~~~~~~~~ Signed-off-by: Amit Kucheria <amit.kucheria@linaro.org> Reported-by: kbuild test robot <lkp@intel.com> Signed-off-by: Daniel Lezcano <daniel.lezcano@linaro.org> Link: https://lore.kernel.org/r/6757a26876b29922929abf64b1c11fa3b3033d03.1590579709.git.amit.kucheria@linaro.org
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.
