2014-05-09pwm: twl: Really disable twl6030 PWMsAxel Lin1-8/+0
Current twl6030_pwm_disable() implementation writes TWL6030_TOGGLE3_REG twice, the second write sets TWL6030_PWMXEN bits so the PWM clock does not disable.

2013-04-23pwm: Constify OF match tablesThierry Reding1-1/+1
A few drivers already annotate this properly. Make the same change for all other OF supporting drivers.

Return proper error instead of 0 if twl6030_pwm_enable() fails. Signed-off-by: Axel Lin <axel.lin@ingics.com> Acked-by: Peter Ujfalusi <peter.ujfalusi@ti.com> Signed-off-by: Thierry Reding <thierry.reding@avionic-design.de>
2013-04-02pwm: twl: Add .owner to struct pwm_opsAxel Lin1-0/+2
Add missing .owner of struct pwm_ops. This prevents the module from being removed from underneath its users. Signed-off-by: Axel Lin <axel.lin@ingics.com> Acked-by: Peter Ujfalusi <peter.ujfalusi@ti.com> Signed-off-by: Thierry Reding <thierry.reding@avionic-design.de>
2013-02-17pwm: twl: Use to_twl() instead of container_of()Johannes Thumshirn1-6/+3
Always use to_twl() for converting into private data instead of container_of(). Signed-off-by: Johannes Thumshirn <morbidrsa@gmail.com> Signed-off-by: Thierry Reding <thierry.reding@avionic-design.de>
2013-01-30pwm: Add can_sleep property to driversFlorian Vaussard1-0/+1
Calls to PWM drivers connected through I2C can sleep. Use the new can_sleep property. Acked-by: Peter Ujfalusi <peter.ujfalusi@ti.com> Signed-off-by: Florian Vaussard <florian.vaussard@epfl.ch> Signed-off-by: Thierry Reding <thierry.reding@avionic-design.de>
2012-11-28pwm: New driver to support PWMs on TWL4030/6030 series of PMICsPeter Ujfalusi1-0/+359
The driver supports the following PWM outputs: TWL4030 PWM0 and PWM1 TWL6030 PWM1 and PWM2 On TWL4030 the PWM signals are muxed. Upon requesting the PWM the driver will select the correct mux so the PWM can be used. When the PWM has been freed the original configuration is going to be restored.
