hwmon: (f75375s) Don't crash the kernel unnecessarily

2013-10-13T23:16:27+00:00

The f75375s driver crashes the kernel if it detects an an internal implementation error. While the detected conditions suggest that there is a bug in the code, the condition is not fatal. Replace BUG() with WARN(). Cc: Riku Voipio Signed-off-by: Guenter Roeck

hwmon: use dev_get_platdata()

2013-08-12T05:10:39+00:00

Use the wrapper function for retrieving the platform data instead of accessing dev->platform_data directly. Signed-off-by: Jingoo Han Signed-off-by: Guenter Roeck

hwmon: Replace SENSORS_LIMIT with clamp_val

2013-01-26T05:03:54+00:00

SENSORS_LIMIT and the generic clamp_val have the same functionality, and clamp_val is more efficient. This patch reduces text size by 9052 bytes and bss size by 11624 bytes for x86_64 builds. Signed-off-by: Guenter Roeck Acked-by: George Joseph Acked-by: Jean Delvare

hwmon: (f75375s) Convert to use devm_ functions

2012-09-24T04:08:31+00:00

Convert to use devm_ functions to reduce code size and simplify the code. Cc: Riku Voipio Signed-off-by: Guenter Roeck

hwmon: (f75375s) Fix warning message seen in some configurations

2012-04-01T17:24:34+00:00

In some configurations, BUG() does not result in an endless loop but returns to the caller. This results in the following compiler warning: drivers/hwmon/f75375s.c: In function 'duty_mode_enabled': drivers/hwmon/f75375s.c:280: warning: control reaches end of non-void function drivers/hwmon/f75375s.c: In function 'auto_mode_enabled': drivers/hwmon/f75375s.c:295: warning: control reaches end of non-void function Fix the warning by returning something sensible after BUG().

hwmon: convert drivers/hwmon/* to use module_i2c_driver()

2012-03-19T01:26:50+00:00

This patch converts the drivers in drivers/hwmon/* to use the module_i2c_driver() macro which makes the code smaller and a bit simpler.

hwmon: (f75375s) Catch some attempts to write to r/o registers

2012-03-02T20:02:23+00:00

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.

hwmon: (f75375s) Properly map the F75387 automatic modes to pwm_enable

2012-03-02T19:56:43+00:00

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.

hwmon: (f75375s) Make pwm*_mode writable for the F75387

hwmon: (f75375s) Fix writes to the pwm* attribute for the F75387

2012-02-28T22:39:47+00:00

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. Signed-off-by: Nikolaus Schulz [guenter.roeck@ericsson.com: Simplified function parameters] Signed-off-by: Guenter Roeck
