| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | OMAP INTC irqchip driver will be moved under drivers/irqchip/ soon but we still have a dependency with mach-omap2 when it comes to idle functions. In order to make it easy to share those function prototypes with OMAP PM code, we introduce this new header. To avoid modifying several board-files and some of the PM-related code, we just include the new header from common.h which was already included by all users of IRQ-related PM code.

Make the code consistent by always panicing whenever it fails to grab any resource.

| | * | | ARM: at91: PIT: Rework probe functionsMaxime Ripard2014-09-03

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.

| | * | | ARM: at91: PIT: Use of_have_populated_dt instead of CONFIG_OFMaxime Ripard2014-09-02

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.
