2012-03-07hwmon: (zl6100) Maintain delay parameter in driver instance dataGuenter Roeck1-4/+6
A global delay parameter has the side effect of being overwritten with 0 if a single ZL2004 or ZL6105 is instantiated. If other chips supported by the same driver are in the system, this will result in access errors for those chips. To solve the problem, keep a per-instance copy of the delay parameter, and do not change the original parameter.

2012-03-02hwmon: (f75375s) Catch some attempts to write to r/o registersNikolaus Schulz1-0/+27
It makes no sense to attempt to manually configure the fan in auto mode, or set the duty cycle directly in closed loop mode. The corresponding registers are then read-only. If the user tries it nonetheless, error out with EINVAL instead of silently doing nothing.

2012-03-02hwmon: (f75375s) Properly map the F75387 automatic modes to pwm_enableNikolaus Schulz1-8/+34
The F75387 supports automatic fan control using either PWM duty cycle or RPM speed values. Make the driver detect the latter mode, and expose the different modes in sysfs as per pwm_enable, so that the user can switch between them. The interpretation of the pwm_enable attribute for the F75387 is adjusted to be a superset of those values used for similar Fintek chips which do not support automatic duty mode, with 2 mapping to automatic speed mode, and moving automatic duty mode to the new value 4. Toggling the duty mode via pwm_enable is currently denied for the F75387, as the chip then simply reinterprets the fan configuration register values according to the new mode, switching between RPM and PWM units, which makes this a dangerous operation. This patch introduces a new pwm mode into the driver. This is necessary because the new mode (automatic pwm mode, 4) may already be enabled by the BIOS, and the driver should not break existing functionality. This was seen on at least one board.

For the F75387, the register holding the current PWM duty cycle value is r/o; changing it requires writing to the fan expect register instead.

2012-02-23hwmon: (f75375s) Fix register write order when setting fans to full speedNikolaus Schulz1-4/+3
By hwmon sysfs interface convention, setting pwm_enable to zero sets a fan to full speed. In the f75375s driver, this need be done by enabling manual fan control, plus duty mode for the F875387 chip, and then setting the maximum duty cycle. Fix a bug where the two necessary register writes were swapped, effectively discarding the setting to full-speed.
