From 1eeec6af0dbb978743de7ffd7224dfe9a695699f Mon Sep 17 00:00:00 2001 From: Dmitry Eremin-Solenikov Date: Fri, 28 Nov 2014 15:57:32 +0100 Subject: [PATCH] ARM: 8233/1: sa1100: switch to hwirq usage Switch internally to using hardware irq numbers (hwirq). In case of GPIO interrupts, hwirq is equal to GPIO number. In case of system interrupts, hwirq is equal to interrupt number in the interrupt controller.
