Yes, that one is equivalent. You can add Acked-by: Pavel Machek <pavel@ucw.cz> Tested-by: Pavel Machek <pavel@ucw.cz> on it. Thanks, Pavel

I hadn't been watching the Droid 4 threads, so I didn't see you were hitting the same problem. I'm assuming the patch will go through the PWM tree, so copying in Thierry. -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

When all the drivers are built-in, timers are not ready and probing fails. Fix that with -EPROBE_DEFFER. Signed-off-by: Pavel Machek <pavel@ucw.cz>
