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. + +Signed-off-by: Joel Porquet <joel@porquet.org> +Cc: Jason Cooper <jason@lakedaemon.net> +Link: http://lkml.kernel.org/r/1435865565-14114-1-git-send-email-joel@porquet.org +Signed-off-by: Thomas Gleixner <tglx@linutronix.de> +--- + drivers/irqchip/irqchip.h | 19 +------------------ + include/linux/irqchip.h | 14 ++++++++++++++ + 2 files changed, 15 insertions(+), 18 deletions(-) + +--- a/drivers/irqchip/irqchip.h ++++ b/drivers/irqchip/irqchip.h +@@ -8,21 +8,4 @@ + * warranty of any kind, whether express or implied. + */ + +-#ifndef _IRQCHIP_H +-#define _IRQCHIP_H +- +-#include <linux/of.h> +- +-/* +- * This macro must be used by the different irqchip drivers to declare +- * the association between their DT compatible string and their +- * initialization function. +- * +- * @name: name that must be unique accross all IRQCHIP_DECLARE of the +- * same file. +- * @compstr: compatible string of the irqchip driver +- * @fn: initialization function +- */ +-#define IRQCHIP_DECLARE(name, compat, fn) OF_DECLARE_2(irqchip, name, compat, fn) +- +-#endif ++#include <linux/irqchip.h> +--- a/include/linux/irqchip.h ++++ b/include/linux/irqchip.h +@@ -11,6 +11,20 @@ + #ifndef _LINUX_IRQCHIP_H + #define _LINUX_IRQCHIP_H + ++#include <linux/of.h> ++ ++/* ++ * This macro must be used by the different irqchip drivers to declare ++ * the association between their DT compatible string and their ++ * initialization function. ++ * ++ * @name: name that must be unique accross all IRQCHIP_DECLARE of the ++ * same file. ++ * @compstr: compatible string of the irqchip driver ++ * @fn: initialization function ++ */ ++#define IRQCHIP_DECLARE(name, compat, fn) OF_DECLARE_2(irqchip, name, compat, fn) ++ + #ifdef CONFIG_IRQCHIP + void irqchip_init(void); + #else |
