From b800885888406f33edfec0eb1cb752292f23de83 Mon Sep 17 00:00:00 2001 From: Ray Jui Date: Mon, 28 May 2018 11:01:34 -0700 Subject: watchdog: sp805: add 'timeout-sec' DT property support Add support for optional devicetree property 'timeout-sec'. 'timeout-sec' is used in the driver if specified in devicetree.
