Subject: Problem with s3c24xx pwm driver
Date: Wed, 23 Sep 2009 18:24:01 +0300 [thread overview]
Message-ID: <200909231824.11671.anarsoul@gmail.com> (raw)
Hi,
I'm encountering very strange problem with s3c24xx pwm driver. I'm using it
with pwm-bl driver. When backlight level is 0, pwm-bl calls pwm_config(0,
period); pwm_disable(), otherwise it calls pwm_config(duty, period);
pwm_enable().
Problem is that after pwm was disabled, it can't be enabled with
pwm_config(duty, period); pwm_enable() for some (but not all) _valid_
duty/period combinations.
pwm-bl works fine if pwm_disable() call is commented out.
Does anybody know how to solve this problem? Any suggestions?
Regards
Vasily
