From 490d8e3cbf60cc4ad874caa8c07e67e14c25a1af Mon Sep 17 00:00:00 2001 From: Ezequiel Garcia Date: Mon, 10 Feb 2014 20:00:30 -0300 Subject: watchdog: orion: Add per-compatible watchdog start implementation To handle differences between SoCs this commit adds per-compatible string start() function for the watchdog kick-off. This is preparation work and makes no functionality changes to the current driver.
