* hwmon: Add devicetree bindings to gpio-fanJamie Lentin2012-09-221-0/+120
| | | | | | | | | | Allow a gpio-fan to be defined in devicetree, see binding documentation for details. Signed-off-by: Jamie Lentin <jm@lentin.co.uk> Acked-by: Andrew Lunn <andrew@lunn.ch> Acked-by: Guenter Roeck <linux@roeck-us.net> Signed-off-by: Jason Cooper <jason@lakedaemon.net>
* hwmon: (gpio-fan) Use struct dev_pm_ops for power managementRafael J. Wysocki2012-07-211-10/+11
| | | | | | | | | | Make the gpio-fan driver define its PM callbacks through a struct dev_pm_ops object rather than by using legacy PM hooks in struct platform_driver. Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl> [linux@roeck-us.net: CONFIG_PM->CONFIG_PM_SLEEP, and remove unnecessary ()] Signed-off-by: Guenter Roeck <linux@roeck-us.net>

* hwmon: convert drivers/hwmon/* to use module_platform_driver()Axel Lin2011-11-261-12/+1
| | | | | | | | | | | | | | | | | | | This patch converts the drivers in drivers/hwmon/* to use the module_platform_driver() macro which makes the code smaller and a bit simpler.

* hwmon: (gpio-fan) Fix fan_ctrl_init error pathAxel Lin2010-11-111-4/+4
| | | | | | | | | | | | | | | In current implementation, the sysfs entries is not removed before return -ENODEV. Creating the sysfs attribute should be the last thing done by the function, after all the rest has been successful. Otherwise there is a small window during which user-space can access the attribute but the driver isn't ready to deal with the requests. Fix it by moving sysfs_create_group to be the last thing done by the function.

* hwmon: add generic GPIO fan driverSimon Guinot2010-10-251-0/+558
This patch adds hwmon support for fans connected to GPIO lines. Platform specific information such as GPIO pinout and speed conversion array (rpm from/to GPIO value) are passed to the driver via platform_data.
