This patch keeps the timer_of_init() only for probing CPU and use the information obtained by timer_of_init() to also initialize the timer_of structure for the rest of CPUs. Since the probing CPU was requested also a per CPU interrupt, and the timer_of_init() has such a mechanism implemented, the patch took also the chance to pass TIMER_OF_IRQ flag to timer_of_init(). Apart from this csky_mptimer_irq variable was removed and information in per CPU timer_of objects was used instead (to->clkevt.irq).

This new argument is a pointer to an object of type struct timer_of and is used in timer_probe(). Based on the flags filled in the struct timer_of object the probing process will parse different DT bindings. Later on the drivers will use the result of this parsing. Even at the moment only few drivers are using this functionality there are other that could be converted to use it.

Even so, there are timers that could work as clocksource only, clockevent only or both. For timers that could work only as clocksource or as clockevent there were used different mechanisms to register one hardware resource to feed a clocksource device and one hardware resource to feed a clockevent device. One of this is: first probed hardware works as clockevent, 2nd probed hardware works as clocksource device. Another one is to have different DT compatible for the same hardware but one to register a clocksource device, another to register a clockevent device. To avoid this, in [1] it was proposed a chosen node mechanism in DT. The changes in this patch integrate the proposals in [1] and goes further. It uses TIMER_OF library and adapt it. It passes to the probing macro arrays of objects of type struct timer_of. We need arrays here to cover the following scenario: One timer driver could be probe 2 times: 1st time to register a physical device to feed a clocksource device, 2nd timer to register another physical device (of the same type with the 1st one registered) but that will feed a clockevent device. If these are 2 different physical devices they are mapped to a different address, they use different clocks and also different IRQ numbers. So for every probe we need a different struct timer_of object. New flags were introduced in this patch to specify the functionality that timer drivers support: - TIMER_OF_TYPE_CE - TIMER_OF_TYPE_CS - TIMER_OF_TYPE_CE_AND_CS. Drivers that could work only as a clocksource could register a minimum struct timer_of array as follows: static struct timer_of to[] = { { .flags = TIMER_OF_TYPE_CS }, { /* sentinel */ } }; drivers that could work only as a clockevent could register a minimum struct timer_of array as follows: static struct timer_of to[] = { { .flags = TIMER_OF_TYPE_CE }, { /* sentinel */ } }; drivers that could work as both clocksource and clockevent at the same time could register a minimum struct timer_of array as follows: static struct timer_of to[] = { { .flags = TIMER_OF_TYPE_CE_AND_CS }, { /* sentinel*/ } }; And these arrays are passed to the probing system via: TIMER_OF_DECLARE() or CLOCKSOURCE_OF_DECLARE() macros. For backward compatibility all the current drivers that are using TIMER_OF library are registered with TIMER_OF_TYPE_CE_AND_CS flag. At the probing time, the probing CPU will call timer_of_probe() -> timer_of_init(). timer_of_init() parses the DT bindings looking for "linux,clocksource" and "linux,clockevent" chosen DT bindings, and is looking into the to[] array, passed via TIMER_OF_DELCARE()/ CLOCKSOURCE_OF_DECLARE(), for a unused entry which matches with the DT bindings (this is done by comparing TIMER_OF_TYPE* probing flags with TIMER_OF_TYPE* flags retrieved from DT). If there is a match the to[] entry will be used for the current probing and the entry is marked as used. to[] entry is considered to be used if to->np is set. Also the used to[] entry is saved into the data field of struct device_node used in the probe. In this way the probing functions of the timer drivers would retrieve the struct timer_of object to be used in the current probe. In case of timers which are registering percpu struct timer_of objects for probing only the percpu timer_of object is used in the probe time. Currently, these kind of drivers are using only the struct timer_of object corresponding to the probing CPU to retrieve DT bindings and then replicate/adapt this information for the other CPUs. All the drivers were adapted to this mechanism using TIMER_OF_TYPE_CE_AND_CS flag for backward compatibility.
