From a8db8cf0d894df5f1dcfd4bce9894e0dbcc01c96 Mon Sep 17 00:00:00 2001 From: Grant Likely Date: Tue, 14 Feb 2012 14:06:54 -0700 Subject: irq_domain: Replace irq_alloc_host() with revmap-specific initializers Each revmap type has different arguments for setting up the revmap. This patch splits up the generator functions so that each revmap type can do its own setup and the user doesn't need to keep track of how each revmap type handles the arguments. This patch also adds a host_data argument to the generators. There are cases where the host_data pointer will be needed before the function returns. ie. the legacy map calls the .map callback for each irq before returning. v2: - Add void *host_data argument to irq_domain_add_*() functions - fixed failure to compile - Moved IRQ_DOMAIN_MAP_* defines into irqdomain.c Signed-off-by: Grant Likely Cc: Rob Herring Cc: Benjamin Herrenschmidt Cc: Thomas Gleixner Cc: Milton Miller Tested-by: Olof Johansson --- drivers/gpio/gpio-mpc8xxx.c | 7 ++----- 1 file changed, 2 insertions(+), 5 deletions(-) (limited to 'drivers/gpio') diff --git a/drivers/gpio/gpio-mpc8xxx.c b/drivers/gpio/gpio-mpc8xxx.c index 9efd59732eeb..149d9876fca8 100644 --- a/drivers/gpio/gpio-mpc8xxx.c +++ b/drivers/gpio/gpio-mpc8xxx.c @@ -364,9 +364,8 @@ static void __init mpc8xxx_add_controller(struct device_node *np) if (hwirq == NO_IRQ) goto skip_irq; - mpc8xxx_gc->irq = - irq_alloc_host(np, IRQ_DOMAIN_MAP_LINEAR, MPC8XXX_GPIO_PINS, - &mpc8xxx_gpio_irq_ops, MPC8XXX_GPIO_PINS); + mpc8xxx_gc->irq = irq_domain_add_linear(np, MPC8XXX_GPIO_PINS, + &mpc8xxx_gpio_irq_ops, mpc8xxx_gc); if (!mpc8xxx_gc->irq) goto skip_irq; @@ -374,8 +373,6 @@ static void __init mpc8xxx_add_controller(struct device_node *np) if (id) mpc8xxx_gc->of_dev_id_data = id->data; - mpc8xxx_gc->irq->host_data = mpc8xxx_gc; - /* ack and mask all irqs */ out_be32(mm_gc->regs + GPIO_IER, 0xffffffff); out_be32(mm_gc->regs + GPIO_IMR, 0); -- cgit v1.2.3-58-ga151
