From 332fd7c4fef5f3b166e93decb07fd69eb24f7998 Mon Sep 17 00:00:00 2001 From: Kevin Cernekee Date: Thu, 6 Nov 2014 22:44:17 -0800 Subject: genirq: Generic chip: Change irq_reg_{readl,writel} arguments Pass in the irq_chip_generic struct so we can use different readl/writel settings for each irqchip driver, when appropriate. Compute (gc->reg_base + reg_offset) in the helper function because this is pretty much what all callers want to do anyway. Compile-tested using the following configurations: at91_dt_defconfig (CONFIG_ATMEL_AIC_IRQ=y) sama5_defconfig (CONFIG_ATMEL_AIC5_IRQ=y) sunxi_defconfig (CONFIG_ARCH_SUNXI=y) tb10x (ARC) is untested.
