Merge branch 'timers/core' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull timer code update from Thomas Gleixner:
 - armada SoC clocksource overhaul with a trivial merge conflict
 - Minor improvements to various SoC clocksource drivers

* 'timers/core' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
  clocksource: armada-370-xp: Add detailed clock requirements in devicetree binding
  clocksource: armada-370-xp: Get reference fixed-clock by name
  clocksource: armada-370-xp: Replace WARN_ON with BUG_ON
  clocksource: armada-370-xp: Fix device-tree binding
  clocksource: armada-370-xp: Introduce new compatibles
  clocksource: armada-370-xp: Use CLOCKSOURCE_OF_DECLARE
  clocksource: armada-370-xp: Simplify TIMER_CTRL register access
  clocksource: armada-370-xp: Use BIT()
  ARM: timer-sp: Set dynamic irq affinity
  ARM: nomadik: add dynamic irq flag to the timer
  clocksource: sh_cmt: 32-bit control register support
  clocksource: em_sti: Convert to devm_* managed helpers

 ---------------------------------------
 
 Required properties:
-- compatible: Should be "marvell,armada-370-xp-timer"
+- compatible: Should be either "marvell,armada-370-timer" or
+  "marvell,armada-xp-timer" as appropriate.
 - interrupts: Should contain the list of Global Timer interrupts and
   then local timer interrupts
 - reg: Should contain location and length for timers register. First
   pair for the Global Timer registers, second pair for the
   local/private timers.
-- clocks: clock driving the timer hardware
 
-Optional properties:
-- marvell,timer-25Mhz: Tells whether the Global timer supports the 25
-  Mhz fixed mode (available on Armada XP and not on Armada 370)
+Clocks required for compatible = "marvell,armada-370-timer":
+- clocks : Must contain a single entry describing the clock input
+
+Clocks required for compatible = "marvell,armada-xp-timer":
+- clocks : Must contain an entry for each entry in clock-names.
+- clock-names : Must include the following entries:
