There are two + * such devices available on the SoC, but it seems that there isn't an + * enumeration class for watchdogs in Linux like there is for RTCs. + * The second is used rather than the first because it uses IRQ 1, + * thereby avoiding all that IRQ 0 problematic nonsense. + * + * I have not tried this driver on a 1480 processor; it might work + * just well enough to really screw things up. + * + * It is a simple timer, and there is an interrupt that is raised the + * first time the timer expires. The second time it expires, the chip + * is reset and there is no way to redirect that NMI. Which could + * be problematic in some cases where this chip is sitting on the HT + * bus and has just taken responsibility for providing a cache block. + * Since the reset can't be redirected to the external reset pin, it is + * possible that other HT connected processors might hang and not reset. + * For Linux, a soft reset would probably be even worse than a hard reset. + * There you have it. + * + * The timer takes 23 bits of a 64 bit register (?) as a count value, + * and decrements the count every microsecond, for a max value of + * 0x7fffff usec or about 8.3ish seconds. + * + * This watchdog borrows some user semantics from the softdog driver, + * in that if you close the fd, it leaves the watchdog running, unless + * you previously wrote a 'V' to the fd, in which case it disables + * the watchdog when you close the fd like some other drivers. + * + * Based on various other watchdog drivers, which are probably all + * loosely based on something Alan Cox wrote years ago. + * + * (c) Copyright 1996 Alan Cox <alan@redhat.com>, All Rights Reserved. + * http://www.redhat.com + * + * This program is free software;
