[Skiboot] [PATCH v2 0/5] Add support for runtime device-tree update for Garrison

[Shilpasri G Bhat]

This patchset exports psatate voltage identifier for each chip and
adds a new opal call to get the latest pstate table whenever OCC
re-initializes the pstate table in HOMER region. The opal-call is
defined generic to expand and use for any future dynamic update
requirement like throttle status collection.

This patchset contains core/fdt changes by Gavin Shan posted in
https://lists.ozlabs.org/pipermail/skiboot/2015-November/002443.html

Changes from V1:
- Rebased on top of core/fdt changes proposed by Gavin Shan, where
  sub-device-tree-blob is created based on the phandle.
- Added documentation to capture device tree changes.

Gavin Shan (3):
  core/fdt: Split flatten_dt_node()
  core/fdt: Allow to specify FDT blob
  core/fdt: OPAL API opal_get_device_tree()

Shilpasri G Bhat (2):
  occ: Export per-chip Vid in device tree
  occ : Add OPAL API opal_get_dynamic_update() to support runtime update
