With the new TCB clocksource driver, atmel platforms are now able to boot without the PIT driver. Allow unselecting it.Yay! Thanks for doing this!Sure! Can you still check the request_irq/free_irq in timer-atmel-tcbclksrc? I'm not sure whether this can work reliably or only because we are before SYSTEM_STATE=RUNNING. In the latter case, I have another way of doing that.Sorry to put it back on the table, but shouldn't we consider adding these irq_disable/enable_action() helpers?I fear that's the only reliable way to do it.
Alexandre told me you had a better implementation (or idea, I don't remember) than what was proposed here [1]. Do you plan to submit something, or should we work on it?
