From 84715dd6c19e058557ab173d327ea65eac0ccb02 Mon Sep 17 00:00:00 2001 From: Shawn Guo Date: Fri, 2 Dec 2011 15:31:11 +0800 Subject: ARM: imx: eliminate macro IMX_GPIO_TO_IRQ() This patch changes all the static gpio irq number assigning with IMX_GPIO_TO_IRQ() to run-time assigning with gpio_to_irq call, and in turn eliminates the macro IMX_GPIO_TO_IRQ().

IRQ_GPIOF() to run-time assigning with gpio_to_irq call, and in turn eliminates these macros.

Now avic init function calls irq_alloc_descs to get irq_base and adds a lenacy irqdomain with the irq_base, so that the mapping between avic irq and Linux irq number can be handled by irqdomain.
