* hwmon: (max6650) Allow fan shutdown and initial rpm targetMike Looijmans2016-09-091-0/+1
| | | | | | | | | | | | | | The fan can be stopped by writing "3" to pwm1_enable in sysfs. Add devicetree property for early initialization of the fan controller to prevent overheating, for example when resetting the board while the fan was completely turned off. Also improve error reporting, I2C failures were ignored while writing new values. Signed-off-by: Mike Looijmans <mike.looijmans@topic.nl> Signed-off-by: Guenter Roeck <linux@roeck-us.net>

* hwmon: (max6650) Drop device detectionJean Delvare2011-05-251-1/+8
| | | | | | | | | | MAX6650 device detection is unreliable, we got reports of false positives. We now have many ways to let users instantiate the devices explicitly, so unreliable detection should be dropped. Signed-off-by: Jean Delvare <khali@linux-fr.org> Acked-by: "Hans J.
