From c08b7b3ef6bf489ddabadc03e050f3db2ea44b5d Mon Sep 17 00:00:00 2001 From: Eric Miao Date: Wed, 6 Jun 2007 06:32:38 +0100 Subject: [PATCH] [ARM] 4435/1: PXA: remove PXA_INTERNAL_IRQS 1. define PXA_GPIO_IRQ_BASE to be right after the internal IRQs, and define PXA_GPIO_IRQ_NUM to be 128 for all PXA2xx variants 2. make the code specific to the high IRQ numbers (32..64) to be PXA27x specific 3. add a function pxa_init_irq_high() to initialize the internal high IRQ chip, the invoke of this function could be moved to PXA27x specific initialization code Signed-off-by: eric miao Signed-off-by: Russell King --- arch/arm/mach-pxa/irq.c | 26 ++++++++++++++++---------- include/asm-arm/arch-pxa/irqs.h | 15 ++++++--------- 2 files changed, 22 insertions(+), 19 deletions(-) diff --git a/arch/arm/mach-pxa/irq.c b/arch/arm/mach-pxa/irq.c index 45ce711..844d3de 100644 --- a/arch/arm/mach-pxa/irq.c +++ b/arch/arm/mach-pxa/irq.c @@ -67,7 +67,7 @@ static struct irq_chip pxa_internal_chip_low = { .set_wake = pxa_set_wake, }; -#if PXA_INTERNAL_IRQS > 32 +#ifdef CONFIG_PXA27x /* * This is for the second set of internal IRQs as found on the PXA27x. @@ -90,6 +90,19 @@ static struct irq_chip pxa_internal_chip_high = { .unmask = pxa_unmask_high_irq, }; +void __init pxa_init_irq_high(void) +{ + int irq; + + ICMR2 = 0; + ICLR2 = 0; + + for (irq = PXA_IRQ(32); irq < PXA_IRQ(64); irq++) { + set_irq_chip(irq, &pxa_internal_chip_high); + set_irq_handler(irq, handle_level_irq); + set_irq_flags(irq, IRQF_VALID); + } +} #endif /* Note that if an input/irq line ever gets changed to an output during @@ -314,7 +327,6 @@ static struct irq_chip pxa_muxed_gpio_chip = { .set_wake = pxa_set_gpio_wake, }; - void __init pxa_init_irq(void) { int irq; @@ -338,8 +350,6 @@ void __init pxa_init_irq(void) #ifdef CONFIG_PXA27x /* And similarly for the extra regs on the PXA27x */ - ICMR2 = 0; - ICLR2 = 0; GFER3 = 0; GRER3 = 0; GEDR3 = GEDR3; @@ -357,12 +367,8 @@ void __init pxa_init_irq(void) set_irq_flags(irq, IRQF_VALID); } -#if PXA_INTERNAL_IRQS > 32 - for (irq = PXA_IRQ(32); irq < PXA_IRQ(PXA_INTERNAL_IRQS); irq++) { - set_irq_chip(irq, &pxa_internal_chip_high); - set_irq_handler(irq, handle_level_irq); - set_irq_flags(irq, IRQF_VALID); - } +#ifdef CONFIG_PXA27x + pxa_init_irq_high(); #endif for (irq = IRQ_GPIO0; irq <= IRQ_GPIO1; irq++) { diff --git a/include/asm-arm/arch-pxa/irqs.h b/include/asm-arm/arch-pxa/irqs.h index dc4e754..a07fe0f 100644 --- a/include/asm-arm/arch-pxa/irqs.h +++ b/include/asm-arm/arch-pxa/irqs.h @@ -55,18 +55,15 @@ #ifdef CONFIG_PXA27x #define IRQ_TPM PXA_IRQ(32) /* TPM interrupt */ #define IRQ_CAMERA PXA_IRQ(33) /* Camera Interface */ - -#define PXA_INTERNAL_IRQS 34 -#else -#define PXA_INTERNAL_IRQS 32 #endif -#define GPIO_2_x_TO_IRQ(x) \ - PXA_IRQ((x) - 2 + PXA_INTERNAL_IRQS) +#define PXA_GPIO_IRQ_BASE (64) +#define PXA_GPIO_IRQ_NUM (128) + +#define GPIO_2_x_TO_IRQ(x) (PXA_GPIO_IRQ_BASE + (x)) #define IRQ_GPIO(x) (((x) < 2) ?
