From 786621308cfbb9421a54773e57dbdbe504c417cc Mon Sep 17 00:00:00 2001 From: Mark Zhang Date: Tue, 16 Oct 2012 16:31:49 +0800 Subject: ARM: tegra30: clk: Fix output_rate overflow Change the type of variable from "unsigned long" to "u64". This avoids the overflow while clock rate calculating.

The above commit caused tegra_init_timer() failing to get the clk reference.
