*	drivers/pwm: add PXA pulse width modulator controller	Robert Jarzmik	2012-02-17	3	-0/+164
\| \| \| \| \| \| \| \| \|	Add PXA embedded pulse width modulator support. The PWM can generate signals from 49.6kHz to 1.625MHz. The driver is for pxa2xx family. The pxa3xx was not handled yet.

*	drivers/pwm: add duty_ns and period_ns to core pwm chip	Robert Jarzmik	2012-02-17	1	-1/+75
\| \| \| \| \| \| \| \| \| \|	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	3	-0/+176
	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>
