From 1ab7ef158dfbaf6314b6660a3e3fb037cba2a1ca Mon Sep 17 00:00:00 2001 From: Shawn Guo Date: Wed, 13 Jun 2012 09:04:03 +0800 Subject: gpio/mxc: move irq_domain_add_legacy call into gpio driver Move irq_domain_add_legacy call from imx*-dt.c into gpio driver and have the gpio driver adopt irqdomain support for both DT and non-DT boot. With all imx platform code converted from static gpio irq number computation to use run-time gpio_to_irq call, we can now use irq_alloc_descs and irqdomain support to dynamically get irq_base and have the mapping between gpio and irq number available without using virtual_irq_start and MXC_GPIO_IRQ_START.
