From bdb08cb2d3491d441dd403dfb88d90ba90fb7232 Mon Sep 17 00:00:00 2001 From: Russell King Date: Mon, 30 Jun 2008 19:47:59 +0100 Subject: [ARM] pxa: allow clk aliases We need to support more than one name+device for a struct clk for a small number of peripherals. We do this by re-using struct clk alias to another struct clk - IOW, if we find that the entry we're using is an alias, we return the aliased entry not the one we found.
