This helper will be useful for irqchip drivers that need to convert DT binding into IRQ fwspec. Signed-off-by: Masahiro Yamada <yamada.masahiro@xxxxxxxxxxxxx> --- This patch is necessary for my GPIO driver. Since it is trivial enough, I hope Marc will allow this to go though the GPIO subsystem. If this patch is rejected, I can copy this function into my GPIO driver, but I'd like to avoid code duplication. include/linux/irqdomain.h | 2 ++ kernel/irq/irqdomain.c | 5 +++-- 2 files changed, 5 insertions(+), 2 deletions(-) diff --git a/include/linux/irqdomain.h b/include/linux/irqdomain.h index 81e4889..440772c 100644 --- a/include/linux/irqdomain.h +++ b/include/linux/irqdomain.h @@ -259,6 +259,8 @@ extern void irq_set_default_host(struct irq_domain *host); extern int irq_domain_alloc_descs(int virq, unsigned int nr_irqs, irq_hw_number_t hwirq, int node, const struct cpumask *affinity); +extern void of_phandle_args_to_fwspec(struct of_phandle_args *irq_data, + struct irq_fwspec *fwspec); static inline struct fwnode_handle *of_node_to_fwnode(struct device_node *node) { diff --git a/kernel/irq/irqdomain.c b/kernel/irq/irqdomain.c index e84b705..e34cd63 100644 --- a/kernel/irq/irqdomain.c +++ b/kernel/irq/irqdomain.c @@ -727,8 +727,8 @@ static int irq_domain_translate(struct irq_domain *d, return 0; } -static void of_phandle_args_to_fwspec(struct of_phandle_args *irq_data, - struct irq_fwspec *fwspec) +void of_phandle_args_to_fwspec(struct of_phandle_args *irq_data, + struct irq_fwspec *fwspec) { int i; @@ -738,6 +738,7 @@ static void of_phandle_args_to_fwspec(struct of_phandle_args *irq_data, for (i = 0; i < irq_data->args_count; i++) fwspec->param[i] = irq_data->args[i]; } +EXPORT_SYMBOL_GPL(of_phandle_args_to_fwspec); unsigned int irq_create_fwspec_mapping(struct irq_fwspec *fwspec) { -- 2.7.4 -- To unsubscribe from this list: send the line "unsubscribe linux-gpio" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
