The init functions do not return any error. They behave as the following: - panic, thus leading to a kernel crash while another timer may work and make the system boot up correctly or - print an error and let the caller unaware if the state of the system Change that by converting the init functions to return an error conforming to the CLOCKSOURCE_OF_RET prototype. Proper error handling (rollback, errno value) will be changed later case by case, thus this change just return back an error or success in the init function.

The timer driver is using some global variables to define some variables it has to use in most of its functions, like the base address. Use some container_of calls to have a single dynamic (and local) variable to hold this content. The only exception is in the !DT case, where the call chain to at91sam926x_ioremap_pit and then at91sam926x_pit_init as init_time makes it hard for the moment to pass the physical address of the timer.

The PIT timer driver until now had a single probe function, disregarding wether it was probed through DT or in the old-style way. This code later on was calling some DT function to retrieve the proper values for its base address, interrupts and clocks. While this was working, it was preventing the usage of CLOCKSOURCE_OF_DECLARE, and the two different probe path were not as clearly separated as they could be. Rework the probe path to take this into account, and switch to CLOCKSOURCE_OF_DECLARE.

Until now, the machines, even when CONFIG_OF was enabled, were calling at91sam926x_ioremap_pit to try to map the PIT address using the defined physical address. Obviously, with DT, it's not appropriate anymore, and some code was added to the function to deal with this case. Unfortunately, this code was conditionned on CONFIG_OF, which can be enabled, even though no DT was actually used, which would result in such a case, to this code being executed, without any reason. Moreover, the logic that was here before to bail out of the function just check in the DT to see if the PIT node is there, which is the case in all our DTSI. All this can be made much more straightforward just by using of_have_populated_dt to bail out.

Now that the only field in struct sys_timer is .init, delete the struct, and replace the machine descriptor .timer field with the initialization function itself. This will enable moving timer drivers into drivers/clocksource without having to place a public prototype of each struct sys_timer object into include/linux; the intent is to create a single of_clocksource_init() function that determines which timer driver to initialize by scanning the device dtree, much like the proposed irqchip_init() at: http://www.spinics.net/lists/arm-kernel/msg203686.html Includes mach-omap2 fixes from Igor Grinberg.

Update AT91SAM9/CAP9 PIT driver to use generic time and clockevent infrastructure: - Clocksource gives sub-microsecond timestamp precision, assuming memory is clocked at over 16 MHz. It's less than a 32 bit counter, unless it's is also generating IRQs. - Clockevent device supports periodic mode only; no oneshot support from this hardware. No IRQs generated unless it's the active clocksource. Later, another timer (probably from a TC module) can provide a oneshot clockevent device to get NO_HZ and High-Res-Timer behavior. This also updates the timekeeping to use the actual master clock rate on the system, instead of compile-time <asm/arch/timex.h> constants matching what Atmel's EK boards use. (Product boards may well differ!) Plus cleanup: rename "*_timer*" symbols to "*_pit*" (there are other timers, but only one PIT); shorter lines; remove needless CPP stuff; make several symbols static; etc. Signed-off-by: NDavid Brownell <dbrownell@users.sourceforge.net> Signed-off-by: NAndrew Victor <linux@maxim.org.za> Signed-off-by: NRussell King <rmk+kernel@arm.linux.org.uk>
