[WATCHDOG] at32ap700x_wdt: add support for boot status and add fix for silicon errata
This patch enables the watchdog to read out the reset cause after a boot and provide this to the user. The driver will now also return -EIO if probed when booting from a watchdog reset. This is due to a silicon errata in the AT32AP700x devices. Detailed description and work-arounds can be found in the errata section of the datasheet avilable from http://www.atmel.com/dyn/products/datasheets.asp?family_id=682 Signed-off-by: Hans-Christian Egtvedt <hcegtvedt@atmel.com> Signed-off-by: Wim Van Sebroeck <wim@iguana.be> Signed-off-by: Andrew Morton <akpm@linux-foundation.org>
