From 4fd9212cb9bad88ec7c8bf5313f53331905f957a Mon Sep 17 00:00:00 2001 From: Andrew Victor Date: Wed, 2 Apr 2008 21:55:19 +0100 Subject: [PATCH] [ARM] 4908/1: [AT91] RTT platform_device fix The RTT-as-RTC driver will search for the user-specified RTT peripheral via ID number (0 .. 1). Therefore if the processor only contains a single RTT peripheral, we need to set its platform_device.id to "0" instead of "-1". Also add the missing platform_device resource for the CAP9 processor. Bug reported by Sedji Gaouaou.
