From 6a01f230339321292cf065551f8cf55361052461 Mon Sep 17 00:00:00 2001 From: Yi Li Date: Wed, 7 Jan 2009 23:14:39 +0800 Subject: Blackfin arch: merge adeos blackfin part to arch/blackfin/ [Mike Frysinger : - handle bf531/bf532/bf534/bf536 variants in ipipe.h - cleanup IPIPE logic for bfin_set_irq_handler() - cleanup ipipe asm code a bit and add missing ENDPROC() - simplify IPIPE code in trap_c - unify some of the IPIPE code and fix style - simplify DO_IRQ_L1 handling with ipipe code - revert IRQ_SW_INT# addition from ipipe merge - remove duplicate get_{c,s}clk() prototypes ] Signed-off-by: Yi Li Signed-off-by: Mike Frysinger Signed-off-by: Bryan Wu --- arch/blackfin/kernel/bfin_gpio.c | 100 +++++++++++++++++++-------------------- 1 file changed, 50 insertions(+), 50 deletions(-) (limited to 'arch/blackfin/kernel/bfin_gpio.c') diff --git a/arch/blackfin/kernel/bfin_gpio.c b/arch/blackfin/kernel/bfin_gpio.c index 2c72b15b71b0..4c14331978f6 100644 --- a/arch/blackfin/kernel/bfin_gpio.c +++ b/arch/blackfin/kernel/bfin_gpio.c @@ -422,13 +422,13 @@ arch_initcall(bfin_gpio_init);
