thermal: intel: int340x: Add locking to int340x_thermal_get_trip_type()

2023-01-25T14:37:21+00:00

In order to prevent int340x_thermal_get_trip_type() from possibly
racing with int340x_thermal_read_trips() invoked by int3403_notify()
add locking to it in analogy with int340x_thermal_get_trip_temp().

thermal: intel: int340x: Protect trip temperature from concurrent updates

2023-01-24T20:28:19+00:00

Trip temperatures are read using ACPI methods and stored in the memory
during zone initializtion and when the firmware sends a notification for
change. This trip temperature is returned when the thermal core calls via
callback get_trip_temp().

But it is possible that while updating the memory copy of the trips when
the firmware sends a notification for change, thermal core is reading the
trip temperature via the callback get_trip_temp(). This may return invalid
trip temperature.

To address this add a mutex to protect the invalid temperature reads in
the callback get_trip_temp() and int340x_thermal_read_trips().

thermal: core: call put_device() only after device_register() fails

2023-01-19T20:06:41+00:00

put_device() shouldn't be called before a prior call to
device_register(). __thermal_cooling_device_register() doesn't follow
that properly and needs fixing. Also
thermal_cooling_device_destroy_sysfs() is getting called unnecessarily
on few error paths.

Fix all this by placing the calls at the right place.

Based on initial work done by Caleb Connolly.

thermal/drivers/imx_sc_thermal: Drop empty platform remove function

2022-12-14T14:27:30+00:00

A remove callback just returning 0 is equivalent to no remove callback
at all. So drop the useless function.

thermal/drivers/k3_j72xx_bandgap: Map fuse_base only for erratum workaround

2022-12-14T14:25:41+00:00

Some of TI's J721E SoCs require a software trimming procedure for the
temperature monitors to function properly. To determine if a particular
J721E is not affected by this erratum, both bits in the WKUP_SPARE_FUSE0
region must be set. Other SoCs, not affected by this erratum, will not
need this region.

Map the 'fuse_base' region only when the erratum fix is needed.
