From 6b617e224dfac0b64ed70dacdac50be6eb78a6a1 Mon Sep 17 00:00:00 2001 From: Feng Tang Date: Tue, 15 Feb 2011 00:13:31 +0800 Subject: x86/platform: Add a wallclock_init func to x86_init.timers ops Some wall clock devices use MMIO based HW register, this new function will give them a chance to do some initialization work before their get/set_time service get called, which is usually in early kernel boot phase.
