2019-04-26watchdog: at91sam9_wdt: Remove now superfluous wdt start and resetStefan Roese1-8/+0
With the new generic function, the scattered other functions are now removed to be replaced by the generic one. The new version also enables the configuration of the watchdog timeout via the DT "timeout-sec" property (if enabled via CONFIG_OF_CONTROL). The watchdog servicing is enabled via CONFIG_WATCHDOG.

2019-04-09arm: at91: Enable watchdog supportStefan Roese1-10/+0
This patch enables and starts the watchdog on the AT91 platform if configured. The WD timeout value is read in the AT91 WD device driver from the DT, using the "timeout-sec" DT property. If not provided in the DT, the default value of 2 seconds is used.

2019-04-09arm: at91: Remove CONFIG_AT91_HW_WDT_TIMEOUTStefan Roese1-1/+3
This patch removes the CONFIG_AT91_HW_WDT_TIMEOUT as its not needed any more. The WD timeout value can be provided via the "timeout-sec" DT property. If not provided this way, the default value of 2 seconds will be used.

2019-04-09watchdog: at91sam9_wdt: Fix WDT setup in at91_wdt_start()Stefan Roese1-12/+14
This patch fixes the timer register setup in at91_wdt_start() to correctly configure the register again. The input timeout value is now in milli-seconds instead of seconds with the new watchdog API. Make sure to take this into account and only use a max timeout value of 16 seconds as appropriate for this SoC. Also the check against a lower timeout value than 0 is removed. This check makes no sense, as the timeout value is unsigned.

2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini1-2/+1
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>
