From abd2363f6a5f1030b935e0bdc15cf917313b3b10 Mon Sep 17 00:00:00 2001 From: Grant Likely Date: Fri, 24 Feb 2012 08:07:06 -0700 Subject: irq_domain/mips: Allow irq_domain on MIPS This patch makes IRQ_DOMAIN usable on MIPS. It uses an ugly workaround to preserve current behaviour so that MIPS has time to add irq_domain registration to the irq controller drivers. The workaround will be removed in Linux v3.6 Signed-off-by: Grant Likely Cc: Ralf Baechle Cc: Rob Herring Cc: Thomas Gleixner Cc: linux-mips@linux-mips.org --- arch/mips/kernel/prom.c | 14 -------------- 1 file changed, 14 deletions(-) (limited to 'arch/mips/kernel/prom.c') diff --git a/arch/mips/kernel/prom.c b/arch/mips/kernel/prom.c index 6b8b4208481e..558b5395795d 100644 --- a/arch/mips/kernel/prom.c +++ b/arch/mips/kernel/prom.c @@ -60,20 +60,6 @@ void __init early_init_dt_setup_initrd_arch(unsigned long start, } #endif -/* - * irq_create_of_mapping - Hook to resolve OF irq specifier into a Linux irq# - * - * Currently the mapping mechanism is trivial; simple flat hwirq numbers are - * mapped 1:1 onto Linux irq numbers.
