It uses the +generic PWM interface thus it is hardware independent. It can be used on +many SoCs, as long as the SoC supplies a PWM line driver that exposes +the generic PWM API. + +Author: Kamil Debski <k.debski@samsung.com> + +Description +----------- + +The driver implements a simple interface for driving a fan connected to +a PWM output. It uses the generic PWM interface, thus it can be used with +a range of SoCs. The driver exposes the fan to the user space through +the hwmon's sysfs interface. |
