From 3f0a820c4c0b4670fb5f164baa5582e23c2ef118 Mon Sep 17 00:00:00 2001 From: Russell King Date: Sat, 31 Jan 2009 10:05:51 +0000 Subject: [ARM] omap: create a proper tree of clocks 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.
