thermal/drivers/qcom/lmh: Add support for sm8150

2022-03-08T20:26:09+00:00

Add compatible to support LMh for sm8150 SoC.
sm8150 does not require explicit enabling for various LMh subsystems.
Add a variable indicating the same as match data which is set for sdm845.
Execute the piece of code enabling various LMh subsystems only if
enable algorithm match data is present.

thermal/drivers/tsens: register thermal zones as hwmon sensors

2022-03-08T20:26:08+00:00

Register thermal zones as hwmon sensors to let userspace read
CPU temperatures using standard hwmon interface.

thermal/drivers/tsens: Add timeout to get_temp_tsens_valid

2021-10-16T18:24:43+00:00

The function can loop and lock the system if for whatever reason the bit
for the target sensor is NEVER valid. This is the case if a sensor is
disabled by the factory and the valid bit is never reported as actually
valid. Add a timeout check and exit if a timeout occurs. As this is
a very rare condition, handle the timeout only if the first read fails.
While at it also rework the function to improve readability and convert
to poll_timeout generic macro.

thermal/drivers/qcom/spmi-adc-tm5: Add support for HC variant

2021-10-15T07:13:55+00:00

The variant of the ADC Thermal Monitor block found in e.g. PM8998 is
"HC", add support for this variant to the ADC TM5 driver in order to
support using VADC channels as thermal_zones on SDM845 et al.

thermal/drivers/tsens: Fix wrong check for tzd in irq handlers

2021-09-21T13:17:11+00:00

Some devices can have some thermal sensors disabled from the
factory. The current two irq handler functions check all the sensor by
default and the check if the sensor was actually registered is
wrong. The tzd is actually never set if the registration fails hence
the IS_ERR check is wrong.

thermal/drivers/qcom/spmi-adc-tm5: Don't abort probing if a sensor is not used

2021-09-09T14:33:29+00:00

adc_tm5_register_tzd() registers the thermal zone sensors for all
channels of the thermal monitor. If the registration of one channel
fails the function skips the processing of the remaining channels
and returns an error, which results in _probe() being aborted.

One of the reasons the registration could fail is that none of the
thermal zones is using the channel/sensor, which hardly is a critical
error (if it is an error at all). If this case is detected emit a
warning and continue with processing the remaining channels.

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.
