From 546c830c90beb7d3e398007715fd1b631c6c060a Mon Sep 17 00:00:00 2001 From: Jean-Christophe PLAGNIOL-VILLARD Date: Sat, 1 Jun 2013 16:40:11 +0200 Subject: ARM: at91: fix at91_extern_irq usage for non-dt boards Since 4b68520dc0ec96153bc0d87bca5ffba508edfcf ARM: at91: add AIC5 support we allocate the at91_extern_irq. This patch makes it static and stores the non-dt extern irq in the soc structure. It is then possible to use a at91_get_extern_irq() function to get the value for outside of the irq driver. It is useful for passing its value to at91_aic_init().
