* hwmon: applesmc: restore accelerometer and keyboard backlight on resumeHenrik Rydberg2009-09-221-12/+26
| | | | | | | | | | | | | | On resume from suspend, the driver currently resets the logical state as if it was brought up from halt. This patch uses the dev_pm_ops.resume/restore methods to synchronize the hardware with the memorized logical state, in effect bringing back the accelerometer and backlight to the state prior to suspend. Works for both suspend to ram and hibernation. The patch has zero effect on the running state.

* drivers/hwmon/adm1021.c: add low_power support for adm1021 driverMichael Abbott2009-09-221-0/+32
| | | | | | | | | | | Occasionally it is helpful to be able to turn a temperature sensor off (for example if it's making unwanted electrical noise).

* drivers/hwmon/adm1021.c: support high precision ADM1023 remote sensorMichael Abbott2009-09-221-24/+23
| | | | | | | | | | | | | | The ADM1023 temperature sensor supports higher resolution for its external sensor (sensitivity of 1/8 deg C). This patch makes this higher resolution available through the appropriate temperature sysfs nodes. Curiously, this functionality was available in the 2.4 kernel driver (but formatted in a less helpful manner).

| | | | | | | | | | | | | | Enable the coretemp driver on an Intel Atom. I'm not sure if the readings are correct, however - on my 330, the driver reports values between 27 and 41 °C (with core1 being about 8°C hotter than core0, given the same load). Maybe the maximum temperature of 100 °C is wrong for Atom CPUs.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This driver adds support for the hardware monitoring features of the WM831x PMICs to the hwmon API. Monitoring is provided for the system voltages supported natively by the WM831x, the chip temperature, the battery temperature and the auxiliary inputs of the WM831x. Currently no alarms are supported, though digital comparators on the WM831x devices would allow these to be provided. Since the auxiliary and battery temperature input scaling depends on the system configuration the value is reported as a voltage to userspace.

* | hwmon: (lm85) Don't bind to Winbond/Nuvoton WPCD377IJean Delvare2009-09-151-0/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The Winbond/Nuvoton WPCD377I is the reduced version of a Super-I/O which emulates the National Semiconductor LM96000 hardware monitoring chips, but without the hardware monitoring part. Instead of plain disabling the emulation, the vendor left the emulated chip visible, but all monitored values are always zero. This is rather confusing for the users. So detect this case and refuse to bind to such fake chips. This fixes lm-sensors ticket #2182: http://www.lm-sensors.org/ticket/2182 Signed-off-by: Jean Delvare <khali@linux-fr.org>

Also, in the case of monolithic kernels, I think the ACPI drivers should take precedence over native drivers, so they should be listed first in Makefile.

* | hwmon-vid: Ignore 6th VID pin of AMD family 0Fh processorsJean Delvare2009-09-151-1/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We had a report about a mainboard for AMD family 0Fh processors not routing the 6th VID pin from the CPU to the hardware monitoring chip. While the vendor should have wired the pin (or, failing that, should have hardwired it to level high rather than low), the fact is that none of these processors are currently known to operate at the lower voltage levels which require the 6th VID pin. So, as a practical workaround, I propose to ignore the 6th VID pin for these CPUs. If this decision ever causes problems, we'll reconsider.

* | hwmon: (abituguru3) Support multiple DMI strings per chip IDAlistair John Strachan2009-09-151-37/+40
|/ | | | | | | | | | | | | | | | | | | | | | | | Most known Abit motherboards have unique uguru chip IDs. However, some "refresh" boards keep the same chip ID but have a different DMI string. As our DMI board string matching is (necessarily) strict, some boards were failing DMI detection, and as the old probe method was also failing, the driver would not load. The only known boards affected by this problem are the IP35 Pro XE (vs IP35 Pro) and the AB9 Pro (vs AB9). Is it not sufficient to relax the match criteria, as some boards (e.g. the AB9 Quad GT) have different uguru chip IDs. This patch replaces the dmi_name string with a NULL terminated array of strings to be matched per uguru chip ID. It has been compile and runtime tested (thanks Rune).

* | hwmon: (tmp401) Add support for TI's TMP401 sensor chipHans de Goede2009-06-153-0/+576
| | | | | | | | | | | | | | | | | | | | | | | | This is a new hwmon driver for TI's TMP401 temperature sensor IC. This driver was written on behalf of an embedded systems vendor under the Linux driver project. It has been tested using a TI TMP401 sample attached to a i2c-tiny-usb adapter. Which was provided by Till Harbaum, many thanks to him for this! Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Jean Delvare <khali@linux-fr.org>

* hwmon: (w83781d) Fix W83782D support (NULL pointer dereference)Jean Delvare2009-05-081-1/+2
| | | | | | | | | | | | Commit 360782dde00a2e6e7d9fd57535f90934707ab8a8 (hwmon: (w83781d) Stop abusing struct i2c_client for ISA devices) broke W83782D support for devices connected on the ISA bus. You will hit a NULL pointer dereference as soon as you read any device attribute. Other devices, and W83782D devices on the SMBus, aren't affected.

* hwmon: sht15 humidity sensor driverJonathan Cameron2009-04-133-0/+703
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Data sheet at: http://www.sensirion.ch/en/pdf/product_information/Datasheet-humidity-sensor-SHT1x.pdf These sensors communicate over a 2 wire bus running a device specific protocol. The complexity of the driver is mainly due to handling the substantial delays between requesting a reading and the device pulling the data line low to indicate that the data is available. This is handled by an interrupt that is disabled under all other conditions. I wasn't terribly clear on the best way to handle this, so comments on that aspect would be particularly welcome! Interpretation of the temperature depends on knowing the supply voltage. If configured in a board config as a regulator consumer this is obtained from the regulator subsystem. If not it should be provided in the platform data. I've placed this driver in the hwmon subsystem as it is definitely a device that may be used for hardware monitoring and with it's relatively slow response times (up to 120 millisecs to get a reading) a caching strategy certainly seems to make sense!

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Asus boards have an ACPI interface for interacting with the hwmon (fan, temperatures, voltages) subsystem; this driver exposes the relevant information via the standard sysfs interface. There are two different ACPI interfaces: - an old one (based on RVLT/RFAN/RTMP) - a new one (GGRP/GITM) Both may be present but there a few cases (my board, sigh) where the new interface is just an empty stub; the driver defaults to the old one when both are present. The old interface has received a considerable testing, but I'm still awaiting confirmation from my tester that the new one is working as expected (hence the debug code is still enabled). Currently all the attributes are read-only, though a (partial) control should be possible with a bit more work.
