Move the pass/fail checks into selftest() calls instead of a separate if
condition. Unconditionally calling pass was wrong.

of_can_translate_address only checks some conditions for address
translation, but does not check other conditions like having range
properties. The checks it does do are redundant with
__of_address_translate. The only difference is printing a message or
not. Since we only have a single caller that does the full translation
anyway, just remove of_can_translate_address and quiet the error
message.

Using non-translatable addresses in platform device names is wrong
because they may not be globally unique. Just use the default naming with
a global index if the address cannot be translated instead.
of_can_translate_address has the same checks as of_translate_address, so
we can remove it here as well.

Move the /memreserve/ processing and dtb memory reservations into
early_init_fdt_scan_reserved_mem. This converts arm, arm64, and powerpc
as they are the only users of early_init_fdt_scan_reserved_mem.
memblock_reserve is safe to call on the same region twice, so the
reservation check for the dtb in powerpc 32-bit reservations is safe to
remove.

Both powerpc and microblaze have the same FDT blob in debugfs feature.
Move this to common location and remove the powerpc and microblaze
implementations. This feature could become more useful when FDT
overlay support is added.
This changes the path of the blob from "$arch/flat-device-tree" to
"device-tree/flat-device-tree".

With libfdt support, we can take advantage of helper accessors in libfdt
for accessing the FDT header data. This makes the code more readable and
makes the FDT blob structure more opaque to the kernel. This also
prepares for removing struct boot_param_header completely.

The kernel FDT functions predate libfdt and are much more limited in
functionality. Also, the kernel functions and libfdt functions are
not compatible with each other because they have different definitions
of node offsets. To avoid this incompatibility and in preparation to
add more FDT parsing functions which will need libfdt, let's first
convert the existing code to use libfdt.
The FDT unflattening, top-level FDT scanning, and property retrieval
functions are converted to use libfdt. The scanning code should be
re-worked to be more efficient and understandable by using libfdt to
find nodes directly by path or compatible strings.

In "Device Tree powered" systems, platform devices are usually massively
populated with of_platform_populate() call, executed at some level of
initcalls, either by generic architecture or by platform-specific code.
There are situations though where certain devices must be created (and
bound with drivers) before all the others. This presents a challenge,
as devices created explicitly would be created again by
of_platform_populate().
This patch tries to solve that issue in a generic way, adding a
"populated" flag for a DT node description. Subsequent
of_platform_populate() will skip such nodes (and its children) in
a similar way to the non-available ones.
This patch also adds of_platform_depopulate() as an operation
complementary to the _populate() one. It removes a platform or an amba
device populated from the Device Tree, together with its all children
(leaving, however, devices without associated of_node untouched)
clearing the "populated" flag on the way.

Commit 75b57ecf9d1d1e17d099ab13b8f48e6e038676be ('of: Make device
nodes kobjects so they show up in sysfs') has turned Device Tree nodes
in kobjects and added a sysfs based representation for Device Tree
nodes. Since the sysfs logic is only available after the execution of
a core_initcall(), the patch took precautions in of_add_property() and
of_remove_property() to not do any sysfs related manipulation early in
the boot process.
However, it forgot to do the same for of_update_property(), which if
used early in the boot process (before core_initcalls have been
called), tries to call sysfs_remove_bin_file(), and crashes:

To fix this problem, we simply skip the sysfs related calls in
of_update_property(), and rely on of_init() to fix up things when it
will be called, exactly as is done in of_add_property() and
of_remove_property().

Currently we get the following kind of errors if we try to use interrupt
phandles to irqchips that have not yet initialized:
irq: no irq domain found for /ocp/pinmux@48002030 !
------------[ cut here ]------------
WARNING: CPU: 0 PID: 1 at drivers/of/platform.c:171 of_device_alloc+0x144/0x184()
Modules linked in:

(of_platform_populate+0x60/0x98)
This is because we're wrongly trying to populate resources that are not
yet available. It's perfectly valid to create irqchips dynamically, so
let's fix up the issue by resolving the interrupt resources when
platform_get_irq is called.
And then we also need to accept the fact that some irqdomains do not
exist that early on, and only get initialized later on. So we can
make the current WARN_ON into just into a pr_debug().
We still attempt to populate irq resources when we create the devices.
This allows current drivers which don't use platform_get_irq to continue
to function. Once all drivers are fixed, this code can be removed.

[ NOTE! This merge effective drops commit 4329b93b283c ("of: Reduce

The of_graph_get_next_endpoint() function was moved and renamed by
commit fd9fdb78a9bf ("[media] of: move graph helpers from
drivers/media/v4l2-core to drivers/of"). It was originally called
v4l2_of_get_next_endpoint() and lived in the file
drivers/media/v4l2-core/v4l2-of.c.
In that original location, it was then fixed to support empty port
nodes by commit b9db140c1e46 ("[media] v4l: of: Support empty port
nodes"), and that commit clashes badly with the dropped "Reduce
intendation" commit. I had to choose one or the other, and decided
that the "Support empty port nodes" commit was more important ]

This makes the generic of_mdiobus_register parse the DT compatible string for
the pattern ethernet-phy-idAAAA.BBBB. If present it should be a value that
matches the phy-id register normally readable through MDIO.
When the ID is given the phy autoprobing is defeated and the phy is
created directly.
This is necessary to support phy's that cannot be autoprobed when
of_mdiobus_register is called. Specifically, my case has the phy in reset at
of_mdiobus_register, the reset is only released once the ethernet driver
starts, before it attaches to the phy.
Tested on ARM Kirkwood with phy id 0x01410e90 (Marvell 88E1318)

of_get_phy_mode() uses a local array to map phy_interface_t values from
include/linux/net/phy.h to a string which is read from the 'phy-mode' or
'phy-connection-type' property. In preparation for exposing the PHY
interface mode through sysfs, perform the following:
- mode phy_modes from drivers/of/of_net.c to include/linux/phy.h such
that it is right below the phy_interface_t enum
- make it a static inline function returning the string such that we can
use it by just including include/linux/net/phy.h
- add a PHY_INTERFACE_MODE_MAX enum value to guard the iteration in
of_get_phy_mode()

Pull devicetree changes from Grant Likely:
"Updates to devicetree core code. This branch contains the following
notable changes:
- add reserved memory binding
- make struct device_node a kobject and remove legacy
/proc/device-tree
- ePAPR conformance fixes
- update in-kernel DTC copy to version v1.4.0
- preparatory changes for dynamic device tree overlays
- minor bug fixes and documentation changes
The most significant change in this branch is the conversion of struct
device_node to be a kobject that is exposed via sysfs and removal of
the old /proc/device-tree code. This simplifies the device tree
handling code and tightens up the lifecycle on device tree nodes.

be some sanity checking whether a DT is even present before parsing the

This patch adds support for static (defined by 'reg' property) reserved
memory regions declared in device tree.
Memory blocks can be reliably reserved only during early boot. This must
happen before the whole memory management subsystem is initialized,
because we need to ensure that the given contiguous blocks are not yet
allocated by kernel. Also it must happen before kernel mappings for the
whole low memory are created, to ensure that there will be no mappings
(for reserved blocks). Typically, all this happens before device tree
structures are unflattened, so we need to get reserved memory layout
directly from fdt.

After the move to having device nodes be proper kobjects the lifecycle
of the node needs to be controlled better.
At first convert of_add_node() in the unflattened functions to
of_init_node() which initializes the kobject so that of_node_get/put
work correctly even before of_init is called.
Afterwards introduce of_node_is_initialized & of_node_is_attached that
query the underlying kobject about the state (attached means kobj
is visible in sysfs)
Using that make sure the lifecycle of the tree is correct at all
times.

The same data is now available in sysfs, so we can remove the code
that exports it in /proc and replace it with a symlink to the sysfs
version.
Tested on versatile qemu model and mpc5200 eval board. More testing
would be appreciated.

Device tree nodes are already treated as objects, and we already want to
expose them to userspace which is done using the /proc filesystem today.
Right now the kernel has to do a lot of work to keep the /proc view in
sync with the in-kernel representation. If device_nodes are switched to
be kobjects then the device tree code can be a whole lot simpler. It
also turns out that switching to using /sysfs from /proc results in
smaller code and data size, and the userspace ABI won't change if
/proc/device-tree symlinks to /sys/firmware/devicetree/base.
v7: Add missing sysfs_bin_attr_init()
v6: Add __of_add_property() early init fixes from Pantelis
v5: Rename firmware/ofw to firmware/devicetree
Fix updating property values in sysfs
v4: Fixed build error on Powerpc
Fixed handling of dynamic nodes on powerpc
v3: Fixed handling of duplicate attribute and child node names
v2: switch to using sysfs bin_attributes which solve the problem of
reporting incorrect property size.

wrong.

Translating an address from a PCI node of the device-tree into a CPU
physical address doesn't require the core PCI support. Those
translations are just related to the device tree itself.
The use case to translate an address from a PCI node without actually
using the PCI core support is when one needs to access the PCI
controller without accessing any PCI devices.
Marvell SoCs, such as Kirkwood, Dove or Armada XP for instance, come
with an IP of a PCI controller. In the registers of this controller
are stored the ID and the revision of a SoC. With this patch it will
be possible to read the SoC ID of a board without any PCI device and
then without the PCI core support.

The of_update_property() is intented to update a property in a node
and if the property does not exist, will add it.
The second search of the property is possibly won't be found, that
maybe removed by other thread just before the second search begain.
Using the __of_find_property() and __of_add_property() instead and
move them into lock operations.

Per the ePAPR v1.1 specification, 'phy-connection-type' is the canonical
property name for describing an Ethernet to PHY connection type. Make
sure that of_get_phy_mode() also attempts to parse that property and
update the comments mentioning 'phy-mode' to also include
'phy-connection-type'.
