pwm: omap-dmtimer: Fix PWM enabling sequence commit 867beb60d131f7a5cde88ba375338285fdc6ddb8 upstream. To configure DM timer in PWM mode the following needs to be set in OMAP_TIMER_CTRL_REG using set_pwm callback: - Set toggle mode on PORTIMERPWM output pin - Set trigger on overflow and match on PORTIMERPWM output pin. - Set auto reload This is a one time configuration and needs to be set before the start of the DM timer. But the current driver tries to set the same configuration for every period/duty cycle update, which is not needed. So move the PWM setup before enabling timer and do not update it in pwm_omap_dmtimer_config().
