Typically we have CLK_OF_DECLARE for cases where a provider needs to be up and running early during boot for hardware that can't probe defer (i.e. timers, irq controllers). Otherwise we should be able to use the standard linux device model to probe clk providers. It looks like the clocksource is using something from CCU, but perhaps CGU isn't "special" and could be using device model. -- Qualcomm Innovation Center, Inc. is a member of Code Aurora Forum, a Linux Foundation Collaborative Project -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
