From 39c7aa9ea9b6175f4313f69ef9f8e0a3a9bba5bb Mon Sep 17 00:00:00 2001 From: Magnus Damm Date: Fri, 20 Jul 2007 12:10:29 +0900 Subject: [PATCH] sh: intc - add support for 7780 This patch converts the cpu specific 7780 setup code to use the new intc controller. Many new vectors are added and also support for external interrupt sense configuration. So with this patch it is now possible to configure external interrupt pins as edge or level triggered using set_irq_type(). No external interrupts are registered by default. Use plat_irq_setup_pins() to select between IRQ or IRL mode. This patch also fixes the Alarm IRQ for the RTC.
