From: Baruch Siach Date: Mon, 25 Jan 2010 10:58:21 +0000 (+0200) Subject: mx25: fix time accounting X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=faed40665d2d81b7e0e537d14ef680ab3da9f22d;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git mx25: fix time accounting The gpt_clk rate function doesn't consider the PER divider. This causes a significant drift in time accounting. Fix this by introducing the correct rate calculation function.
