From 1611f872513735ac7105535689c0dd668fbf1c04 Mon Sep 17 00:00:00 2001 From: Andrew Lunn Date: Sat, 17 Nov 2012 15:22:28 +0100 Subject: ARM: Kirkwood: switch to DT clock providers With true DT clock providers available switch Kirkwood clock setup in DT- enabled boards. While AUXDATA can be removed completely from bus probing, some devices still don't know about DT. Therefore, some clkdev aliases are created until these devices also move to DT.
