* spi: prefix modalias with "spi:"Anton Vorontsov2009-09-23
| | | | | | | | | | | | | | | | | | | | | This makes it consistent with other buses (platform, i2c, vio, ...). I'm not sure why we use the prefixes, but there must be a reason. This was easy enough to do it, and I did it.

* hwmon: applesmc: restore accelerometer and keyboard backlight on resumeHenrik Rydberg2009-09-22
| | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Delvare2009-09-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Strachan2009-09-15
|/ | | | | | | | | | | | | | | | | | | | | | | | 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: (f71882fg) Cleanup f8000 pwm handlingHans de Goede2009-06-15
| | | | | | | | | | | | | | | | | | | | | | | | Currently we are using separate per model sysfs attr for the 3th pwm, because the 3th pwm of the f8000 only has automatic mode and not manual mode. Doing things this way was getting in the way for adding f71858fg support, so this patch makes the pwm attr identical for all models, and instead adds a check to store_pwm_enable() disallowing setting the 3th pwm to manual mode on a f8000 IC.

* | hwmon: PCI quirk for hwmon access on MSI MS-7031 boardJean Delvare2009-06-15
| | | | | | | | | | | | | | | | | | | | | | | | | | The MSI MS-7031 is based on an ATI IXP300 south bridge. On this south bridge, accessible I/O ports must be enabled explicitly. Unfortunately the BIOS forgets to enable access to the hardware monitoring chip I/O ports, so hardware monitoring fails. Add a quirk enabling access to the required ports (0x295-0x296). This is exactly what MSI's own hardware monitoring application is doing, so it has to be the right way. Signed-off-by: Jean Delvare <khali@linux-fr.org>
* | hwmon: (w83627ehf) Add W83627DHG-P supportJean Delvare2009-06-15
| | | | | | | | | | | | | | | | | | | | Add support for the new incarnation of the Winbond/Nuvoton W83627DHG chip known as W83627DHG-P. It is basically the same as the original W83627DHG with an additional automatic can speed control mode (not supported by the driver yet.)

| | | | | | | | | | | | | | | | | | | | | | | | | | This adds support for TI's TMP411 sensor chip. Preliminary support were done by Gabriel Konat, Sander Leget and Wouter Willems. The chip is compatible with TI's TMP401 sensor chip. It has additional support for historical minimun/maximum measurements.

| | | | | | | | | | | | | | | | | | | | | | | | 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>

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 Cameron2009-04-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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!
