From cf8ff6b6ab0e99dd3058852f4ec76a6140abadec Mon Sep 17 00:00:00 2001 From: Feng Tang Date: Thu, 10 Nov 2011 13:42:02 +0000 Subject: x86/platform: Add a wallclock_init func to x86_platforms 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.
