Having a call like arch_timer_get_rate() to check whether there is a DT node for the timer doesn't seem right, can you refactor the code to provide some has_arch_timer_node() or similar call instead, so it's a bit easier to understand & maintain at least?
Good point, thanks for the guidance. I will introduce has_arch_timer_node() as you said and use it as follows: if (has_arch_timer_node()) clocksource_of_init(); esle arch_timer_acpi_init(); /* try ACPI way */ Is this make sense to you?
