Devicetree updates for v4.21:
- Initial support for DT bindings using json-schema language. This is
the start of converting DT bindings from free-form text to a
structured format.
- Reworking of initrd address initialization. This moves to using the
phys address instead of virt addr in the DT parsing code. This rework
was motivated by CONFIG_DEV_BLK_INITRD causing unnecessary rebuilding
of lots of files.
- Fix stale phandle entries in phandle cache
- DT overlay validation improvements. This exposed several memory leak
bugs which have been fixed.
- Use node name and device_type helper functions in DT code
- Last remaining conversions to using %pOFn printk specifier instead of
device_node.name directly
- Create new common RTC binding doc and move all trivial RTC devices out
of trivial-devices.txt.
- New bindings for Freescale MAG3110 magnetometer, Cadence Sierra PHY,
and Xen shared memory
- Update dtc to upstream version v1.4.7-57-gf267e674d145
of: __of_detach_node() - remove node from phandle cache
Non-overlay dynamic devicetree node removal may leave the node in
the phandle cache. Subsequent calls to of_find_node_by_phandle()
will incorrectly find the stale entry. Remove the node from the
cache.
Add paranoia checks in of_find_node_by_phandle() as a second level
of defense (do not return cached node if detached, do not add node
to cache if detached).
Fixes: 0b3ce78e90fc ("of: cache phandle nodes to reduce cost of of_find_node_by_phandle()")
