Actually the update_irq_enable api was incorrectly implemented by the original author since the chip does not have support for the 1/sec update timer interrupt. The chip only has hardware support for alarms and supports reading/setting time. support for update_irq_enable needs to be removed from the code. -- To unsubscribe from this list: send the line "unsubscribe linux-tegra" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
