+Subject: [PATCH 170/203] clocksource: armada-370-xp: Get reference fixed-clock
+ by name
+
+The Armada XP timer has two mandatory clock inputs: nbclk and refclk,
+as specified by the device-tree binding.
+
+This commit fixes the clock selection. Instead of hard-coding the clock
+rate for the 25 MHz reference fixed-clock, obtain the clock by its name.
