2009-01-07hwmon: Don't overuse I2C_CLIENT_MODULE_PARMJean Delvare1-1/+4
I2C_CLIENT_MODULE_PARM is overkill for force_subclients. We really only use 4 out of the 48 slots, so we're better defining a custom variable instead. This change saves 92 bytes of data for each of the five drivers affected.

2008-10-17hwmon: (w83791d) fan 4/5 pins can also be used for gpioMarc Hulsman1-3/+27
Pins fan/pwm 4-5 can be in use as GPIO. If that is the case, do not create their sysfs-interface. Signed-off-by: Marc Hulsman <m.hulsman@tudelft.nl> Acked-by: Hans de Goede <j.w.r.degoede@hhs.nl> Signed-off-by: Jean Delvare <khali@linux-fr.org>

2008-08-06hwmon: (w83791d) Use fan divisor bits from vbat registerMarc Hulsman1-4/+20
Update w83791d with fan bits in vbat mon register (7.48 of the datasheet). This change allows all fans to have a divisor of 128, and fixes a problem with incorrectly reported fan speeds. Signed-off-by: Marc Hulsman <m.hulsman@tudelft.nl> Signed-off-by: Jean Delvare <khali@linux-fr.org>

2008-02-07hwmon: VRM is not written to registersJean Delvare1-4/+2
What was true of reading the VRM value is also true of writing it: not being a register value, it doesn't need hardware access, so we don't need a reference to the i2c client. This allows for a minor code cleanup. As gcc appears to be smart enough to simplify the generated code by itself, this cleanup only affects the source code, the generated binaries are unchanged.

2007-10-09hwmon: VRM is not read from registersJean Delvare1-1/+1
The VRM value is not read from chip registers, so there's no need to update the device data cache before exporting the VRM value to user-space. Signed-off-by: Jean Delvare <khali@linux-fr.org> Acked-by: Hans de Goede <j.w.r.degoede@hhs.nl> Signed-off-by: Mark M. Hoffman <mhoffman@lightlink.com>

2006-09-28w83791d: Documentation updateCharles Spirakis1-3/+4
w83791d: Documentation update The alarm bits and the beep enable bits are in different positions in the hardware. Document the problem and leave it to the user-space code to handle the situation. When this driver is updated to the standardized sysfs alarm/beep methodology, this won't be a problem. This is a documentation only change.

Add support for the w83791d sensor chip. The w83791d hardware is somewhere between the w83781d and the w83792d and this driver code is derived from the code that supports those chips.
