81f47d4eea fdt_slicer: bump to SI_ORDER_THIRD following r347183
r347183 bumped GEOM classes to SI_ORDER_SECOND to resolve a race between
them and the initialization of devsoftc.mtx in devinit, but missed this
dependency on g_flashmap that may now lose the race against GEOM
classes/g_init.

There's a great comment that describes the situation that has also been
updated with the new ordering of GEOM classes.

786bc5a275 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

2ef79738b1 cpsw: use phy-handle in FDT to find PHY address
In r337703 DTS files were updated to Linux 4.18, including Linux commit
4d8b032d3c03f4e9788a18bbb51b10e6c9e8a56b which removed the `phy_id`
property from am335x-bone-common (as the property was deprecated).

Use `phy-handle` via fdt_get_phyaddr, keeping the existing code as a
fallback for old DTBs.

985f00a61c fdt: Explicitly mark fdt_slicer as dependent on geom_flashmap

9fa3d98b88 Add support to fdt_slicer for the new style partition data documented in
devicetree/bindings/mtd/partition.txt.

In the old style, all the children of the device node which did not have a
compatible property were the partitions.  In the new style, there is a child
node of the device which has a compatible string of "fixed-partitions", and
its children are the individual partitions.

Also, support the read-only property by setting the corresponding slice flag.

3308d36a5e 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.

1252c9346c Clean up OF_getprop_alloc API
OF_getprop_alloc takes element size argument and returns number of
elements in the property. There are valid use cases for such behavior
but mostly API consumers pass 1 as element size to get string
properties. What API users would expect from OF_getprop_alloc is to be
a combination of malloc + OF_getprop with the same semantic of return
value. This patch modifies API signature to match these expectations.

For the valid use cases with element size != 1 and to reduce
modification scope new OF_getprop_alloc_multi function has been
introduced that behaves the same way OF_getprop_alloc behaved prior to
this patch.

less/equal to 0 which is also wrong because phandle_t is unsigned

1537078d8f sys/dev: further adoption of SPDX licensing ID tags.
Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

Change is required for the alignment of Marvell Armada 38x

Summary:
NXP/Freescale, among others, includes an optional cell-index property
on nodes to denote the SoC block number of the node.  This can be useful if, for
example, a node is disabled or nonexistent in the fdt, or the blocks are not
organized in address-sorted order.  For instance, on the P1022, DMA2 is located
at CCSR offset 0xC000, while DMA1 is located at 0x21000.
