From 0bc6791707694c77b3543de39f77972a65de917a Mon Sep 17 00:00:00 2001 From: Florian Fainelli Date: Sun, 31 Oct 2010 23:49:58 +0100 Subject: MIPS: AR7: Fix loops per jiffies on TNETD7200 devices TNETD7200 run their CPU clock faster than the default CPU clock we assume. In order to have the correct loops per jiffies settings, initialize clocks right before setting mips_hpt_frequency. As a side effect, we can no longer use msleep in clocks.c which requires other parts of the kernel to be initialized, so replace these with mdelay.
