find_node_by_full_name() does the same thing as of_find_node_by_path(),
but takes no locks and doesn't work on aliases. Refactor
of_find_node_opts_by_path() into __of_find_node_by_full_path() and
replace find_node_by_full_name() with it.

Several places in DT code open code the equivalent of kbasename.
Replace them.
The behavior for root nodes in node_name_cmp will be slightly different.
Instead of comparing "/", "" will be compared. The comparison will be
the same.

base.c contains both core OF functions and increasingly other
functionality such as accessing properties and graphs, including
convenience functions. In the near future this would also include OF
specific implementation of the fwnode property and graph APIs.
Create driver/of/property.c to contain procedures for accessing and
interpreting device tree properties. The procedures are moved from
drivers/of/base.c, with no changes other than copying only the includes
required by the moved procedures.

of_find_node_by_phandle.

The OF graph API leaves too much of the graph walking to clients when
in many cases the driver doesn't care about accessing the port or
endpoint nodes. The drivers typically just want the device connected via
a particular graph connection. of_graph_get_remote_node provides this
functionality.

During stepping down the tree, parent node is gotten first and its refcount is
increased with of_node_get() in __of_get_next_child(). Since it just being used
as tmp node, its refcount must be decreased with of_node_put() after traversing
its child nodes.
Or, its refcount will never be descreased to ZERO, then it will never be freed,
as well as other related memory blocks.
To fix this, decrease refcount of parent with of_node_put() after
__of_find_node_by_path().

It is useful to have helper function just to get the number of cache
levels for a given logical cpu. We can obtain the same by just checking
the level at which the last cache is present. This patch adds support
to find the level of the last cache for a given cpu.
It will be used on ARM64 platform where the device tree provides the
information for the additional non-architected/transparent/external
last level caches that are not integrated with the processors.

When allocating a struct alias_prop, of_alias_scan() only requested that
it be aligned on a 4 byte boundary. The struct contains pointers which
leads to us attempting 64 bit writes on 64 bit systems, and if the CPU
doesn't support unaligned memory accesses then this causes problems -
for example on some MIPS64r2 CPUs including the "mips64r2-generic" QEMU
emulated CPU it will trigger an address error exception.
Fix this by requesting alignment for the struct alias_prop allocation
matching that which the compiler expects, using the __alignof__ keyword.

Currently platforms/drivers needing to get the machine model name are
replicating the same snippet of code. In some case, the OF reference
counting is either missing or incorrect.
This patch adds support to read the machine model name either using
the "model" or the "compatible" property in the device tree root node
to the core OF/DT code.
This can be used to remove all the duplicate code snippets doing exactly
same thing later.

This reverts commit 05fd007e4629 ("console: don't prefer first
registered if DT specifies stdout-path").
The reverted commit changes existing behavior on which many ARM boards
rely. Many ARM small-board-computers, like e.g. the Raspberry Pi have
both a video output and a serial console. Depending on whether the user
is using the device as a more regular computer; or as a headless device
we need to have the console on either one or the other.
Many users rely on the kernel behavior of the console being present on
both outputs, before the reverted commit the console setup with no
console= kernel arguments on an ARM board which sets stdout-path in dt
would look like this:
[root@localhost ~]# cat /proc/consoles
ttyS0 -W- (EC p a) 4:64
tty0 -WU (E p ) 4:1
Where as after the reverted commit, it looks like this:
[root@localhost ~]# cat /proc/consoles
ttyS0 -W- (EC p a) 4:64
This commit reverts commit 05fd007e4629 ("console: don't prefer first
registered if DT specifies stdout-path") restoring the original
behavior.

If a device tree specifies a preferred device for kernel console output
via the stdout-path or linux,stdout-path chosen node properties or the
stdout alias then the kernel ought to honor it & output the kernel
console to that device. As it stands, this isn't the case. Whilst we
parse the stdout-path properties & set an of_stdout variable from
of_alias_scan(), and use that from of_console_check() to determine
whether to add a console device as a preferred console whilst
registering it, we also prefer the first registered console if no other
has been selected at the time of its registration.
This means that if a console other than the one the device tree selects
via stdout-path is registered first, we will switch to using it & when
the stdout-path console is later registered the call to
add_preferred_console() via of_console_check() is too late to do
anything useful. In practice this seems to mean that we switch to the
dummy console device fairly early & see no further console output:
Console: colour dummy device 80x25
console [tty0] enabled
bootconsole [ns16550a0] disabled
Fix this by not automatically preferring the first registered console if
one is specified by the device tree. This allows consoles to be
registered but not enabled, and once the driver for the console selected
by stdout-path calls of_console_check() the driver will be added to the
list of preferred consoles before any other console has been enabled.
When that console is then registered via register_console() it will be
enabled as expected.

Add a new set of array reading functions that take a minimum and
maximum size limit and will fail if the property size is not within
the size limits. This makes it more convenient for drivers that
use variable-size DT arrays which must be bounded at both ends -
data must be at least N entries but must not overflow the array
it is being copied into. It is also more efficient than making this
functionality out of existing public functions and avoids duplication.
The existing array functions have been left in the API, since there
are a very large number of clients of those functions and their
existing functionality is still useful. This avoids turning a small
API improvement into a major kernel rework.
The old functions have been turned into mininmal static inlines calling
the new functions. The old functions had no upper limit on the actual
size of the dts entry, to preserve this functionality rather than keeping
two near-identical implementations, if the new function is called with
max=0 there is no limit on the size of the dts entry but only the min
number of elements are read.

Fix a memory leak resulting from memory allocation in safe_name().
This patch fixes all call sites of safe_name().
Mathieu Malaterre reported the memory leak on boot:
On my PowerMac device-tree would generate a duplicate name:
[ 0.023043] device-tree: Duplicate name in PowerPC,G4@0, renamed to "l2-cache#1"
in this case a newly allocated name is generated by `safe_name`. However
in this case it is never deallocated.
The bug was found using kmemleak reported as:

The validity of the property input argument to of_remove_property() is
never checked within the function and thus it is possible to pass a null
value. It happens that this will be picked up in __of_remove_property()
as no matching property of the device node will be found and thus an
error will be returned, however once again there is no explicit check
for a null value. By the time this is detected 2 locks have already been
acquired which is completely unnecessary if the property to remove is
null.
Add an explicit check in the function of_remove_property() for a null
property value and return -ENODEV in this case, this is consistent with
what the previous return value would have been when the null value was
not detected and passed to __of_remove_property().
By moving an explicit check for the property paramenter into the
of_remove_property() function, this will remove the need to perform this
check in calling code before invocation of the of_remove_property()
function.

With this macro any user can easily iterate over a list of

Pull drm updates from Dave Airlie:
"This is the main drm pull request for v4.2.
I've one other new driver from freescale on my radar, it's been posted
and reviewed, I'd just like to get someone to give it a last look, so
maybe I'll send it or maybe I'll leave it.
There is no major nouveau changes in here, Ben was working on
something big, and we agreed it was a bit late, there wasn't anything
else he considered urgent to merge.
There might be another msm pull for some bits that are waiting on
arm-soc, I'll see how we time it.

to the build in various configs,t hat I just applied.
Summary:
New drivers:
- virtio-gpu:
KMS only pieces of driver for virtio-gpu in qemu.
This is just the first part of this driver, enough to run

Commit 5590f3196b29 ("drivers/core/of: Add symlink to device-tree from
devices with an OF node") adds the symlink `of_node` for each device
pointing to it's device tree node while creating/initialising it.
However the devicetree sysfs is created and setup in of_init which is
executed at core_initcall level. For all the devices created before
of_init, the following error is thrown:
"Error -2(-ENOENT) creating of_node link"
Like many other components in driver model, initialize the sysfs support
for OF/devicetree from driver_init so that it's ready before any devices
are created.
