* | drivers/pwm: add duty_ns and period_ns to core pwm chip | Robert Jarzmik | 2012-02-17 | 1 | -1/+6 |
| | | | | | | | | | | Add variables to control the duty_ns and period_ns of PWM chips. When these variables are set, a call to either pwm_enable() or pwm_config() is performed to enforce the setup values.

* | Add pwm core support | Sascha Hauer | 2012-02-17 | 1 | -0/+63 |
This patch adds framework support for PWM (pulse width modulation) devices. A new pwm can be registered from a hardware driver using pwmchip_add(). It can then be requested from a client driver using pwm_request(). A string is used as a unique identifier for the pwms. It should usually be initialized by the hardware drivers using dev_name(dev). The client API is the same as currently in the Linux Kernel. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> |
