From f0997a9518145dc5c30963c74f248e8eac10591b Mon Sep 17 00:00:00 2001 From: Benjamin Herrenschmidt Date: Fri, 14 Nov 2014 17:55:03 +1100 Subject: [PATCH] of/base: Fix PowerPC address parsing hack commit 746c9e9f92dde2789908e51a354ba90a1962a2eb upstream. We have a historical hack that treats missing ranges properties as the equivalent of an empty one. This is needed for ancient PowerMac "bad" device-trees, and shouldn't be enabled for any other PowerPC platform, otherwise we get some nasty layout of devices in sysfs or even duplication when a set of otherwise identically named devices is created multiple times under a different parent node with no ranges property. This fix is needed for the PowerNV i2c busses to be exposed properly and will fix a number of other embedded cases.
