hwmon: (it87) Properly decode -128 degrees C temperature

2009-03-12T12:36:39Z

The it87 driver is reporting -128 degrees C as +128 degrees C. That's not a terribly likely temperature value but let's still get it right, especially when it simplifies the code. Signed-off-by: Jean Delvare

hwmon: Check for ACPI resource conflicts

2009-01-07T15:37:35Z

Check for ACPI resource conflicts in hwmon drivers. I've included all Super-I/O and PCI drivers. I've voluntarily left out: * Vendor-specific drivers: if they conflicted on any system, this would pretty much mean that they conflict on all systems, and we would know by now. * Legacy ISA drivers (lm78 and w83781d): they only support chips found on old designs were ACPI either wasn't supported or didn't deal with thermal management. * Drivers accessing the I/O resources indirectly (e.g. through SMBus): the checks are already done where they belong, i.e. in the bus drivers.

hwmon: (it87) Add support for the ITE IT8720F

2009-01-07T15:37:32Z

Allow it87.c to handle IT8720 chipset like IT8718 in order to retrieve voltage, temperatures and fans speed from sensors tools. Also updating the related documentation. Signed-off-by: Jean-Marc Spaggiari Signed-off-by: Jean Delvare

hwmon: (it87) Fix thermal sensor type values

2008-10-17T15:51:16Z

The it87 driver doesn't follow the standard sensor type values as documented in Documentation/hwmon/sysfs-interface. It uses value 2 for thermistors instead of value 4. This causes "sensors" to tell the user that the chip is setup for a transistor while it is actually setup for a thermistor. Using value 4 for thermistors solves the problem. For compatibility reasons, we still accept value 2 but emit a warning message so that users update their configuration files. Signed-off-by: Jean Delvare Acked-by: Hans de Goede

hwmon: (it87) Prevent power-off on Shuttle SN68PT

2008-10-09T13:33:58Z

On the Shuttle SN68PT, FAN_CTL2 is apparently not connected to a fan, but to something else. One user has reported instant system power-off when changing the PWM2 duty cycle, so we disable it. I use the board name string as the trigger in case the same board is ever used in other systems. This closes lm-sensors ticket #2349: pwmconfig causes a hard poweroff http://www.lm-sensors.org/ticket/2349 Signed-off-by: Jean Delvare

hwmon: (it87) Fix fan tachometer reading in IT8712F rev 0x7 (I)

2008-09-20T08:25:19Z

The IT8712F v0.9.1 datasheet applies to revisions >= 0x8 (J). The driver was incorrectly attempting to enable 16-bit fan readings on rev 0x7 (I) which led to incorrect RPM values. Signed-off-by: Andrew Paprocki Tested-by: John Gumb Signed-off-by: Jean Delvare

hwmon: (it87) Support for 16-bit fan reading in it8705 >= rev 0x03

2008-08-06T20:41:06Z

The it8705 chip supports 16-bit fan tachometers in revisions at least >= 0x03 (Version G). This patch enables 16-bit fan readings on all revisions >= 0x03 just like the it8712, it8716, and it8718 chips. Signed-off-by: Andrew Paprocki Signed-off-by: Jean Delvare

hwmon: (it87) Support for 16-bit fan reading in it8712 >= rev 0x07

2008-08-06T20:41:06Z

The it8712 chip supports 16-bit fan tachometers in revisions >= 0x07. Revisions >= 0x08 dropped support for 8-bit fan divisor registers. The patch enables 16-bit fan readings on all revisions >= 0x07 just like the it8716 and it8718 chips. Signed-off-by: Andrew Paprocki Signed-off-by: Jean Delvare

hwmon: (it87) Delete pwmN_freq files on driver removal

2008-02-08T01:39:43Z

In commit f8d0c19a93cea3a26a90f2462295e1e01a4cd250 I forgot to delete the pwmN_freq files on driver removal, here's the fix. Signed-off-by: Jean Delvare Acked-by: Riku Voipio Signed-off-by: Mark M. Hoffman
