   4 Subject: [PATCH] irqchip: Move IRQCHIP_DECLARE macro to
   5  include/linux/irqchip.h
   6
   7 At the moment the IRQCHIP_DECLARE macro is only declared locally in
   8 drivers/irqchip/irqchip.h. It prevents from using it directly in arch/*
   9 directories whenever irqchip drivers only exist there, which happens in a few
  10 cases (e.g. arc, arm, microblaze and mips).
  11
  12 This patch makes the macro to be globally defined, i.e. in
  13 include/linux/irqchip.h, and thus usable for arch-specific declarations of
  14 irqchip drivers. In this way, it is very similar to what clocksource does (ie
  15 CLOCKSOURCE_OF_DECLARE is defined in include/linux/clocksource.h).
  16
  17 For now, this patch only moves the declaration of the macro
  18 IRQCHIP_DECLARE to the global header 'include/linux/irqchip.h' and make
  19 'drivers/irqchip/irqchip.h' include 'include/linux/irqchip.h'. Later, other
  20 patches will get rid of 'drivers/irqchip/irqchip.h' and modify all the impacted
  21 irqchip drivers.
