From bf9006399939762e6cd32445e848e56727df9d98 Mon Sep 17 00:00:00 2001 From: Damien Riegel Date: Tue, 8 Dec 2015 11:37:28 -0500 Subject: watchdog: ts4800: add driver for TS-4800 watchdog This watchdog is instantiated in a FPGA that is memory mapped. It is made of only one register, called the feed register. Writing to this register will re-arm the watchdog for a given time (and enable it if it was disable). It can be disabled by writing a special value into it. It is part of a syscon block, and the watchdog register offset in this block varies from board to board. This offset is passed in the syscon property after the phandle to the syscon node.
