From 132b16325fae0742a02075894af16197e83febe8 Mon Sep 17 00:00:00 2001 From: Russell King Date: Mon, 13 Dec 2010 13:14:55 +0000 Subject: ARM: AT91: update clock source registration In d7e81c2 (clocksource: Add clocksource_register_hz/khz interface) new interfaces were added which simplify (and optimize) the selection of the divisor shift/mult constants. Switch over to using this new interface.
