From d47fbb5996269f3081deb7a1b4ba717557256555 Mon Sep 17 00:00:00 2001 From: Florian Fainelli Date: Wed, 15 Jul 2009 12:09:34 +0200 Subject: [PATCH] MIPS: AR7: Make board code register ar7_wdt as a platform device This patch makes the board code register the ar7_wdt driver as a platform device. We move the dynamic resource calculation here since the driver should not be aware of the AR7 SoC version it is running on.
