pbias device stopped having memory resource after
"ARM: dts: <platform>: add minimal l4 bus layout with control module
support" got merged. This results in platform_get_resource returning
-EINVAL in pbias driver. This is because address translation fails
while trying to convert the address to resource which happens
during the device creation process during boot up.
Even though after [1], reg property in pbias dt node is un-used,
it might be an issue if we plan to use it at a later point of time.
Patch series is created on top of [1].
[1] -> https://lkml.org/lkml/2015/9/3/51
Verified the address in omap4 panda, omap5 uevm and dra72 boards.

commit <72b10ac00eb1> ("ARM: dts: omap24xx: add minimal l4 bus
layout with control module support") moved pbias_regulator dt node
from being a child node of ocp to be the child node of
scm_conf. Since scm_conf doesn't have the 'ranges' property,
address translation fails while trying to convert the address
to resource. Fix it here.

Your other series is obviously needed for v4.3.. But seems these
are also needed for stable? If so, which versions, v4.2+?
Can you please just do a single patch with multiple Fixes tags
as they fix regression for multiple commits? Doing tons of one
liner patches for the same thing just creates commit log noise..
Remember to not Cc stable when posting, I'll add that tag when
committing if needed.
Regards,
Tony

Both the series are needed from v4.1+. However since the 'reg' property
is not going to be used, I'm not sure if this series has to be marked
for stable.
