hwmon: (da9052) Synchronize access with mfd

2020-05-13T17:06:09+00:00

When tsi-as-adc is configured it is possible for in7[0123]_input read to
return an incorrect value if a concurrent read to in[456]_input is
performed. This is caused by a concurrent manipulation of the mux
channel without proper locking as hwmon and mfd use different locks for
synchronization.

Switch hwmon to use the same lock as mfd when accessing the TSI channel.

hwmon: (nct7904) Fix incorrect range of temperature limit registers

2020-05-13T14:24:51+00:00

The format of temperature limitation registers are 8-bit 2's complement
and the range is -128~127.
Converts the reading value to signed char to fix the incorrect range
of temperature limitation registers.

hwmon: (nct7904) Read all SMI status registers in probe function

2020-05-13T14:23:11+00:00

When nct7904 power up, it compares current sensor readings against the
default threshold immediately. This results in false alarms on startup.
Read all SMI status registers in probe function to clear the alarms.

hwmon: (drivetemp) Fix SCT support if SCT data tables are not supported

2020-05-09T20:22:34+00:00

If SCT is supported but SCT data tables are not, the driver unnecessarily
tries to fall back to SMART. Use SCT without data tables instead in this
situation.

hwmon: (jc42) Fix name to have no illegal characters

2020-04-18T17:13:07+00:00

The jc42 driver passes I2C client's name as hwmon device name. In case
of device tree probed devices this ends up being part of the compatible
string, "jc-42.4-temp". This name contains hyphens and the hwmon core
doesn't like this:

jc42 2-0018: hwmon: 'jc-42.4-temp' is not a valid name attribute, please fix

This changes the name to "jc42" which doesn't have any illegal
characters.

hwmon: (k10temp) make some symbols static

Fix the following sparse warning:

drivers/hwmon/k10temp.c:189:12: warning: symbol 'k10temp_temp_label' was
not declared. Should it be static?
drivers/hwmon/k10temp.c:202:12: warning: symbol 'k10temp_in_label' was
not declared. Should it be static?
drivers/hwmon/k10temp.c:207:12: warning: symbol 'k10temp_curr_label' was

hwmon: (drivetemp) Return -ENODATA for invalid temperatures

2020-04-12T22:12:51+00:00

Holger Hoffstätte observed that Samsung 850 Pro may return invalid
temperatures for a short period of time after resume. Return -ENODATA
to userspace if this is observed.

hwmon: (drivetemp) Use drivetemp's true module name in Kconfig section

2020-04-12T22:12:51+00:00

The addition of the support for reading the temperature of ATA drives as
per commit 5b46903d8bf3 ("hwmon: Driver for disk and solid state drives
with temperature sensors") lists in the respective Kconfig section the
name of the module to be optionally built as "satatemp".

However, building the kernel modules with "CONFIG_SENSORS_DRIVETEMP=m",
does not generate a file named "satatemp.ko".

Instead, the rest of the original commit uses the term "drivetemp" and
a file named "drivetemp.ko" ends up in the kernel's modules directory.
This file has the right ingredients:

	$ strings /path/to/drivetemp.ko | grep ^description
	description=Hard drive temperature monitor

and modprobing it produces the expected result:

	# drivetemp is not loaded
	$ sensors -u drivetemp-scsi-4-0
	Specified sensor(s) not found!
	$ sudo modprobe drivetemp
	$ sensors -u drivetemp-scsi-4-0
	drivetemp-scsi-4-0
	Adapter: SCSI adapter
	temp1:
	  temp1_input: 35.000
	  temp1_max: 60.000
	  temp1_min: 0.000
	  temp1_crit: 70.000
	  temp1_lcrit: -40.000
	  temp1_lowest: 20.000
	  temp1_highest: 36.000

Fix Kconfig by referring to the true name of the module.

change email address for Pali Rohár

2020-04-10T22:36:22+00:00

For security reasons I stopped using gmail account and kernel address is
now up-to-date alias to my personal address.

People periodically send me emails to address which they found in source
code of drivers, so this change reflects state where people can contact
me.
