4d846d260e spdx: The BSD-2-Clause-FreeBSD identifier is obsolete, drop -FreeBSD
The SPDX folks have obsoleted the BSD-2-Clause-FreeBSD identifier. Catch
up to that fact and revert to their recommended match of BSD-2-Clause.

79794d5c18 extres: syscon: pull in sys/malloc.h (fix !FDT)
syscon currently includes sys/malloc.h via header pollution from
dev/ofw/ofw_bus.h -> dev/ofw/openfirm.h.  Fix the build without FDT
defined by including sys/malloc.h directly.

e35c28a24b syscon: Add syscon_get_by_ofw_node
This allow to get a syscon node defined under a specific fdt node (which isn't
always the device one).

01d0f9c0e4 Refine locking inside of syscon driver.
In some cases, the syscon driver may be used by consumer requiring better
control about locking (ie. it may be used as registe file provider for clock
driver which needs locked access to multiple registers).
Add fine locking protocol methods together with bunch of helper functions
in syscon driver and implement this functionality in syscon_generic driver.

7f8c4c78f5 Add method for getting of syscon handle from parent device.
If simple multifuction device also provides syscon interface, its
childern should be able to consume it. Due to this:
- declare coresponding method in syscon interface
- implement it in simple multifunction device driver

removed.

f7604b1b27 Align OF_getencprop_alloc API with OF_getencprop and OF_getprop_alloc
Change OF_getencprop_alloc semantics to be combination of malloc and
OF_getencprop and return size of the property, not number of elements
allocated.

For the use cases where number of elements is preferred introduce
OF_getencprop_alloc_multi helper function that copies semantics
of OF_getencprop_alloc prior to this change.

This is to make OF_getencprop_alloc and OF_getencprop_alloc_multi
function signatures consistent with OF_getencprop_alloc and
OF_getencprop_alloc_multi.

Functionality-wise this patch is mostly rename of OF_getencprop_alloc
to OF_getencprop_alloc_multi except two calls in ofw_bus_setup_iinfo
where 1 was used as a block size.

198ca831a1 extres/syscon: Commit missing bits from r327106
r327106 introduced kobj to syscon so it can be subclassed and fit in with
the rest of the syscon framework. The diff for syscon.c was misapplied in a
clean tree prior to commit, so bring it back to what was included in the
review and tested. The entire file has basically been rewritten from what
was present prior to the kobj work.

cd04523f0e Move syscon into extres framework
This should help reduce confusion between syscon/syscons a little bit.
syscon is a resource generally modeled by FDT platforms, and not to be
confused with syscons.
