From 2af29b78618ac8b3a8746337002f108f8fdf56ad Mon Sep 17 00:00:00 2001 From: Andrew Victor Date: Wed, 11 Feb 2009 21:23:10 +0100 Subject: [ARM] 5390/1: AT91: Watchdog fixes The recently merged AT91SAM9 watchdog driver uses the AT91SAM9X_WATCHDOG config variable, whereas the original version of the driver (and the platform support code) used AT91SAM9_WATCHDOG. This causes the watchdog platform_device to never be registered, and therefore the driver not to be initialized. This patch: - updates the platform support code to use AT91SAM9X_WATCHDOG. - includes to fix compile error (same fix as was applied to at91rm9200_wdt.c) - fixes comment regarding watchdog clock-rates in at91rm9200.
