   4 Subject: [PATCH 173/203] ARM: mvebu: Add the reference 25 MHz fixed-clock to
   5  Armada XP
   6
   7 The Armada XP SoC has a reference 25 MHz fixed-clock that is used in
   8 some controllers such as the timer and the watchdog. This commit adds
   9 a DT representation of this clock through a fixed-clock compatible node.
