From 8832b20093434514fda5e8a0c885270eda4fbf40 Mon Sep 17 00:00:00 2001 From: Ivan Khoronzhuk Date: Wed, 4 Dec 2013 21:39:30 +0200 Subject: watchdog: davinci: reuse driver for keystone arch The keystone arch uses the same IP watchdog, so add "ti,keystone-wdt" compatible and correct identity. The Keystone arch is using clocks in DT and source clock for watchdog has to be specified, so add this to binding.
