Merge tag 'timer' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Pull "ARM: timer cleanup work" from Arnd Bergmann:
 "These are split out from the generic soc and driver updates because
  there was a lot of conflicting work by multiple people.  Marc Zyngier
  worked on simplifying the "localtimer" interfaces, and some of the
  platforms are touching the same code as they move to device tree based
  booting.

  Signed-off-by: Arnd Bergmann <arnd@arndb.de>"

+* ARM Timer Watchdog
+
+ARM 11MP, Cortex-A5 and Cortex-A9 are often associated with a per-core
+Timer-Watchdog (aka TWD), which provides both a per-cpu local timer
+and watchdog.
+
+The TWD is usually attached to a GIC to deliver its two per-processor
+interrupts.
+
+** Timer node required properties:
+
+- compatible : Should be one of:
+	"arm,cortex-a9-twd-timer"
+	"arm,cortex-a5-twd-timer"
+	"arm,arm11mp-twd-timer"
+
+- interrupts : One interrupt to each core
+
+- reg : Specify the base address and the size of the TWD timer
+	register window.
+
+Example:
+
+	twd-timer@2c000600 {
+		compatible = "arm,arm11mp-twd-timer"";
+		reg = <0x2c000600 0x20>;
+		interrupts = <1 13 0xf01>;
+	};
+
+** Watchdog node properties:
+
+- compatible : Should be one of:
+	"arm,cortex-a9-twd-wdt"
+	"arm,cortex-a5-twd-wdt"
+	"arm,arm11mp-twd-wdt"
+
+- interrupts : One interrupt to each core
+
+- reg : Specify the base address and the size of the TWD watchdog
+	register window.
+
+Example:
+
+	twd-watchdog@2c000620 {
+		compatible = "arm,arm11mp-twd-wdt";
+		reg = <0x2c000620 0x20>;
+		interrupts = <1 14 0xf01>;
