From fffa051281f7cb2729abe584d111e064f609f2ab Mon Sep 17 00:00:00 2001 From: Shawn Guo Date: Mon, 19 May 2014 20:19:06 +0800 Subject: ARM: imx5: tzic_init_irq() can directly be .init_irq hook After i.MX51 supports DT only, tzic_init_irq() can figure out the tzic_base on its own. Thus, it can directly be .init_irq hook, and mx51[53]_init_irq() can be saved.
