From e9b98f6040f5a7a04d659759d83ea28d9c528800 Mon Sep 17 00:00:00 2001 From: Paul Walmsley Date: Tue, 26 Jan 2010 20:12:57 -0700 Subject: [PATCH] OMAP clock: make the fixed divisor clock code available for all OMAPs One of the OMAP1 clocks can use the fixed divisor recalculation code introduced in the OMAP2 clock code, so rename the omap2_fixed_divisor_recalc() function to omap_fixed_divisor_recalc() and make it available to all OMAPs. A followup patch converts the OMAP1 clock.
