Subject: [PATCH] irqchip: Move IRQCHIP_DECLARE macro to
|
|
include/linux/irqchip.h
|
|
|
|
At the moment the IRQCHIP_DECLARE macro is only declared locally in
|
|
drivers/irqchip/irqchip.h. It prevents from using it directly in arch/*
|
|
directories whenever irqchip drivers only exist there, which happens in a few
|
|
cases (e.g. arc, arm, microblaze and mips).
|
|
|
|
This patch makes the macro to be globally defined, i.e. in
|
|
include/linux/irqchip.h, and thus usable for arch-specific declarations of
|
|
irqchip drivers. In this way, it is very similar to what clocksource does (ie
|
|
CLOCKSOURCE_OF_DECLARE is defined in include/linux/clocksource.h).
|
|
|
|
For now, this patch only moves the declaration of the macro
|
|
IRQCHIP_DECLARE to the global header 'include/linux/irqchip.h' and make
|
|
'drivers/irqchip/irqchip.h' include 'include/linux/irqchip.h'. Later, other
|
|
patches will get rid of 'drivers/irqchip/irqchip.h' and modify all the impacted
|
|
irqchip drivers.
