Merge tag 'devicetree-for-linus' of git://git.secretlab.ca/git/linux
Pull device tree updates from Grant Likely:
"This branch contains the following changes:
- Removal of CONFIG_OF_DEVICE, it is always enabled by CONFIG_OF
- Remove #ifdef from linux/of_platform.h to increase compiler syntax
coverage
- Bug fix for address decoding on Bimini and js2x powerpc platforms.
- miscellaneous binding changes
One note on the above. The binding changes going in from all kinds of
different trees has gotten rather out of hand. I picked up some
during this cycle, but even going though my tree isn't a great fit.
Ian Campbell has prototyped splitting the bindings and .dtb files into
a separate repository. The plan is to migrate to using that sometime
in the next few kernel releases which should get rid of a lot of the
churn on binding docs and .dts files"
