Hi, This is the WDT driver for Toshiba's ARM SoC, Visconti[0]. This has not yet been included in Linux kernel, but patches have been posted [1] and some patches have been applied [2]. Since this is a SoC driver, this cannot work by itself, but I have confirmed that it works with the patch series sent as [1] with DT setting.
