*	PWM: Implement devicetree support	Sascha Hauer	2014-02-28	1	-7/+64
\| \| \| \| \| \|	This implements of_pwm_request() for PWM client drivers. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
*	PWM: Add functions for getting/setting period/duty cycle	Sascha Hauer	2014-02-28	1	-0/+20
\| \| \| \|	Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
*	PWM: Add i.MX PWM driver	Sascha Hauer	2014-02-14	3	-1/+270
\| \| \| \| \| \| \|	The Kernel driver from Linux-3.13 with some adjustments for barebox. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
*	PWM: pxa: use pwmx as devname	Sascha Hauer	2014-02-14	1	-1/+1
\| \| \| \| \| \| \|	As this changes the name of the pwm we also have to adjust it in pwm_request. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
*	PWM: Use a separate device for PWMs	Sascha Hauer	2014-02-13	1	-5/+15
\| \| \| \| \| \| \| \|	Instead of directly using the hardware devicet for PWMs register a logical PWM device so that the user operates on pwmx devices rather than pxa-pwmx. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
*	pwm: sanity check values before passing them to the drivers	Sascha Hauer	2013-09-27	1	-0/+7
\| \| \| \| \| \| \| \| \|	Check for valid period size before calling ops->config. This fixes the pxa driver which otherwise does a division by zero. While at it, also check for duty_ns being smaller or equal to period_ns. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Cc: Robert Jarzmik <robert.jarzmik@free.fr>
*	pwm: Use dev_add_param_int for pwm parameters	Sascha Hauer	2013-04-11	1	-59/+30

*	switch all platform_bus device/driver registering to ↵	Jean-Christophe PLAGNIOL-VILLARD	2012-10-04	1	-1/+1
\| \| \| \| \| \| \| \|	platform_driver/device_register now register_driver and register_device are for bus only usage. Signed-off-by: Jean-Christophe PLAGNIOL-VILLARD <plagnioj@jcrosoft.com>
*	Treewide: remove address of the Free Software Foundation	Sascha Hauer	2012-09-17	1	-4/+0
\| \| \| \| \| \| \|	The FSF address has changed in the past. Instead of updating it each time the address changes, just drop it completely treewide. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
*	pwm PXA: Compile only on PXA	Sascha Hauer	2012-07-25	1	-0/+1
\| \| \| \| \| \| \|	The PXA PWM driver does not compile on any other architecture, so depend on PXA. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
*	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. Signed-off-by: Robert Jarzmik <robert.jarzmik@free.fr> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
*	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>
