From 926b65e20dc336391dc333309d34bdf7d5fa3f3b Mon Sep 17 00:00:00 2001 From: Ivan Khoronzhuk Date: Mon, 10 Feb 2014 12:10:57 +0200 Subject: [PATCH] clocksource: keystone: add bindings for keystone timer This patch provides bindings for the 64-bit timer in the KeyStone architecture devices. The timer can be configured as a general-purpose 64-bit timer, dual general-purpose 32-bit timers. When configured as dual 32-bit timers, each half can operate in conjunction (chain mode) or independently (unchained mode) of each other. It is global timer is a free running up-counter and can generate interrupt when the counter reaches preset counter values.
