Subject: [PATCH 73/86] [ARM] omap: create a proper tree of clocks
Date: Thu, 12 Mar 2009 11:28:23 -0700 [thread overview]
Message-ID: <1236882516-29403-74-git-send-email-khilman@deeprootsystems.com> (raw)
In-Reply-To: <1236882516-29403-73-git-send-email-khilman@deeprootsystems.com>
From: Russell King <rmk@dyn-67.arm.linux.org.uk>
Traditionally, we've tracked the parent/child relationships between
clk structures by setting the child's parent member to point at the
upstream clock. As a result, when decending the tree, we have had
to scan all clocks to find the children.
Avoid this wasteful scanning by keeping a list of the clock's children.
