2009-03-25[WATCHDOG] rc32434_wdt: add timeout module parameterPhil Sutter1-16/+31
The WDT timer ticks quite fast (half of the CPU clock speed, which may be between 198MHz and 330MHz (or 400MHz on newer boards)). Given it's size of 32Bit, the maximum timeout value ranges from about 21s to 43s, depending on the configured CPU clock speed. This patch add's the timeout module parameter and checks that it's not bigger then the maximum timeout for the given clock speed.

2009-02-24[WATCHDOG] rc32434_wdt: fix watchdog driverPhil Sutter1-94/+64
The existing driver code wasn't working. Neither the timeout was set correctly, nor system reset was being triggered, as the driver seemed to keep the WDT alive himself. There was also some unnecessary code. Signed-off-by: Phil Sutter <n0-1@freewrt.org> Signed-off-by: Wim Van Sebroeck <wim@iguana.be> Cc: stable <stable@kernel.org>
