hwmon: (tmp401) Do not auto-detect chip on I2C address 0x37

2015-05-29T20:37:06+00:00

I2C address 0x37 may be used by EEPROMs, which can result in false
positives. Do not attempt to detect a chip at this address.

hwmon: (it87) Add support for IT8620E

2015-04-05T13:01:00+00:00

IT8620E is mostly compatible to IT7828F. Add generic support for it.

IT8620E supports up to 6 fan tachometers and 6 pwm controls.
Support for the 6th tachometer and for the additional pwm controls
are addded in separate patches.

hwmon: (it87) Add support for IT8790E

2015-04-05T13:00:59+00:00

IT8790E is a super-IO chip with three fan tachometers. It is mostly
compatible to IT8728F, but only supports three fan tachometers
instead of five.

hwmon: Add Nuvoton NCT7904 hwmon driver

2015-03-09T16:59:36+00:00

The NCT7904D is a hardware monitor supporting up to 20 voltage sensors,
internal temperature sensor, Intel PECI and AMD SB-TSI CPU temperature
interface, up to 12 fan tachometer inputs, up to 4 fan control channels
with SmartFan.

hwmon: (jc42) Add support for additional IDT temperature sensors

2015-03-09T16:59:35+00:00

TS3000GB0 has a new device ID (0x2913). Since IDT's datasheets suggest
that the upper 8 bit of the device ID reflect the chip ID and the lower
8 bit reflect the version number, modify the code to accept all chips
with ID 0x29xx.

Also add support for TS3001 and TSE2004.

Some of the datasheets for older chips are no longer available from
the IDT web site, so replace explicit links in the documentation with
a generic note.

hwmon: (it87) Add support for IT8781F

2015-03-09T16:59:35+00:00

IT8781F is mostly compatible to IT8782F. Major difference is that it only
supports four instead of six UART channels, and therefore does not share
the uart6 pins.

hwmon: (ina2xx) Add ina231 compatible string

2015-01-26T05:23:59+00:00

Add support for "ina231" as compatible string, and update
Documentation and Kconfig accordingly.

Tested with the Exynos5422-based odroid-xu3 board which has on-board
INA231 sensors.

hwmon: (ina2xx) implement update_interval attribute for ina226

2015-01-26T05:23:59+00:00

This attribute allows to configure the update interval of ina226. Although
the bus and shunt voltage conversion times remain hardcoded to 1.1 ms, we can
now modify said interval by changing the averaging rate.

While we're at it - add an additional variable to ina2xx_data, which holds
the current configuration settings - this way we'll be able to restore the
configuration in case of an unexpected chip reset.

hwmon: (ina2xx) make shunt resistance configurable at run-time

2015-01-26T05:23:59+00:00

The shunt resistance can only be set via platform_data or device tree. This
isn't suitable for devices in which the shunt resistance can change/isn't
known at boot-time.

Add a sysfs attribute that allows to read and set the shunt resistance.
