pwm: samsung: Fix kernel warning while unexporting a channel

2013-11-01T10:17:57Z

PWM channel data was set to NULL before freeing it. This caused the following kernel warning while unexporting the channel. Set the channel data to NULL after freeing it.

pwm: add ep93xx PWM support

2013-10-17T14:07:19Z

Remove the non-standard EP93xx PWM driver in drivers/misc and add a new driver for the PWM controllers on the EP93xx platform based on the PWM framework. These PWM controllers each support 1 PWM channel with programmable duty cycle, frequency, and polarity inversion.

pwm: don't use devm_pinctrl_get_select_default() in probe

2013-10-15T10:16:35Z

Since commit ab78029 (drivers/pinctrl: grab default handles from device core), we can rely on device core for setting the default pins. Compile tested only. Acked-by: Linus Walleij (personally at LCE13) Signed-off-by: Wolfram Sang Signed-off-by: Thierry Reding
