From ae278a935f086775e8ae31a8ec9f7224ea25ea3c Mon Sep 17 00:00:00 2001 From: Stephen Warren Date: Mon, 19 Nov 2012 16:41:20 -0700 Subject: 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 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.
