From 41f3103fcfffff096c34f5267d7c9a26b44d89d3 Mon Sep 17 00:00:00 2001 From: Russell King <rmk@dyn-67.arm.linux.org.uk> Date: Thu, 19 Feb 2009 13:25:16 +0000 Subject: [PATCH] [ARM] omap: fix clock reparenting in omap2_clk_set_parent() When changing the parent of a clock, it is necessary to keep the clock use counts balanced otherwise things the parent state will get corrupted. Since we already disable and re-enable the clock, we might as well use the recursive versions instead.
