From 687e16bc2f9231334942cc41febc27d666b07299 Mon Sep 17 00:00:00 2001 From: Darren Stevens Date: Wed, 31 Aug 2016 13:24:45 +0100 Subject: [PATCH] powerpc/pasemi: Fix device_type of Nemo SB600 node. The of_node for the SB600 (io-bridge) has its device_type set to 'io-bridge' Set it to 'isa' so that it can be found by isa_bridge_find_early() instead of using patches in the kernel.
