From a2bd4fd17926d715a470fbe0ebe05128ba410984 Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Fri, 23 Jun 2006 01:44:10 -0700 Subject: [SPARC64]: Add of_device layer and make ebus/isa use it. Sparcspkr and power drivers are converted, to make sure it works. Eventually the SBUS device layer will use this as a sub-class. I really cannot cut loose on that bit until sparc32 is given the same infrastructure. Signed-off-by: David S.
