From e6f740f59693d9a997daeef8fbe7351e6641b743 Mon Sep 17 00:00:00 2001 From: Janusz Krzysztofik Date: Wed, 28 Apr 2010 01:07:42 +0000 Subject: [PATCH] OMAP1: Amstrad Delta: use FIQ for processing GPIO interrupts The patch adds initialization of FIQ related handlers to the Amstrad Delta videophone board code. FIQ will be used instead of a traditional IRQ for processing all GPIO generated interrupts, including a keyboard serial clock line.
