2010-08-14hwmon: (pc87427) Add support for manual fan speed controlJean Delvare
Add initial support for PWM outputs of the PC87427 Super-I/O chip. Only mode change and manual fan speed control are supported. Automatic mode configuration isn't supported, and won't be until at least one board is known, which makes uses of the PWM outputs.

2010-08-14hwmon: (pc87427) Handle disabled fan inputs properlyJean Delvare
Most fan input pins of the PC87427 can have alternate functions. Update the driver to check the configuration register and only support fan inputs which are really used for fan monitoring. Signed-off-by: Jean Delvare <khali@linux-fr.org> Acked-by: Guenter Roeck <guenter.roeck@ericsson.com>
2010-08-14hwmon: (w83627ehf) Add support for W83667HG-BGuenter Roeck

2010-08-14hwmon: (w83627ehf) Driver cleanupGuenter Roeck
- Moved fan pwm register array pointers into per-instance data. - Only read fan pwm data for installed/supported fans. - Update fan max output and fan step output information from data in registers. - Create max_output and step_output attribute files only if respective fan pwm registers exist.

2010-08-14hwmon: Add driver for SMSC EMC2103 temperature monitor and fan controllerSteve Glendinning
SMSC's EMC2103 family of temperature/fan controllers have 1 onboard and up to 3 external temperature sensors, and allow closed-loop control of one fan. This patch adds support for them. Signed-off-by: Steve Glendinning <steve.glendinning@smsc.com> Signed-off-by: Jean Delvare <khali@linux-fr.org>
2010-08-14hwmon: Remove in[0-*]_fault from sysfs-interfaceJean Delvare
Fault files are for hardware failures that can be reported. So far we've seen chips reporting such failures for temperature sensors and fans, but not for voltages. Remove in[0-*]_fault for now. It can be added back later if really needed, but I doubt it. Signed-off-by: Jean Delvare <khali@linux-fr.org> Acked-by: Guenter Roeck <guenter.roeck@ericsson.com>

Add currX_alarm, currX_min_alarm, currX_max_alarm and currX_beep attributes to the hwmon sysfs API. currX_min_alarm and currX_max_alarm are already supported by the LTC4215 and LTC4245 drivers. currX_alarm is supported by the LTC4261 driver.

2010-08-14hwmon: (it87) Export labels for internal sensorsJean Delvare
Some voltage sensors can be wired internally to the IT87xxF chip's own power supply channels. In that case, we can inform user-space that the wiring is known by exporting proper labels for these sensors. Signed-off-by: Jean Delvare <khali@linux-fr.org>

2010-08-14hwmon: (ltc4245) Expose all GPIO pins as analog voltagesIra W. Snyder
Add support for exposing all GPIO pins as analog voltages. Though this is not an ideal use of the chip, some hardware engineers may decide that the LTC4245 meets their design requirements when studying the datasheet. The GPIO pins are sampled in round-robin fashion, meaning that a slow reader will see stale data. A userspace application can detect this, because it will get -EAGAIN when reading from a sysfs file which contains stale data. Users can choose to use this feature on a per-chip basis by using either platform data or the OF device tree (where applicable). Signed-off-by: Ira W. Snyder <iws@ovro.caltech.edu> Signed-off-by: Jean Delvare <khali@linux-fr.org>
2010-08-14hwmon: (pc87360) Fix device resource declarationJean Delvare
It's not OK to call platform_device_add_resources() multiple times in a row. Despite its name, this functions sets the resources, it doesn't add them. So we have to prepare an array with all the resources, and then call platform_device_add_resources() once. Before this fix, only the last I/O resource would be actually registered. The other I/O resources were leaked. Signed-off-by: Jean Delvare <khali@linux-fr.org> Cc: Jim Cromie <jim.cromie@gmail.com> Cc: stable@kernel.org

Move the if(err) statement after the if into the if branch indicated by its indentation. The preceding if(err) test implies that err cannot be nonzero unless the if branch is taken.

2010-08-13[IA64] Fix 64-bit atomic routines to return "long"Tony Luck
These have been broken (returning "int") since the dawn of time.

2010-08-13time: Workaround gcc loop optimization that causes 64bit div errorsJohn Stultz
Early 4.3 versions of gcc apparently aggressively optimize the raw time accumulation loop, replacing it with a divide. On 32bit systems, this causes the following link errors: undefined reference to `__umoddi3' undefined reference to `__udivdi3' The gcc issue has been fixed in 4.4 and greater.
