+Subject: [PATCH 77/79] clocksource: add common of_clksrc_init() function
+
+It is desirable to move all clocksource drivers to drivers/clocksource,
+yet each requires its own initialization function. We'd rather not
+pollute <linux/> with a header for each function. Instead, create a
+single of_clksrc_init() function which will determine which clocksource
+driver to initialize based on device tree.
+
+Based on a similar patch for drivers/irqchip by Thomas Petazzoni.
