of/fdt: mark hotpluggable memory
When movable nodes are enabled, any node containing only hotpluggable memory is made movable at boot time. On x86, hotpluggable memory is discovered by parsing the ACPI SRAT, making corresponding calls to memblock_mark_hotplug(). If we introduce a dt property to describe memory as hotpluggable, configs supporting early fdt may then also do this marking and use movable nodes.

of_mdio: add helper to deregister fixed-link PHYs
Add helper to deregister fixed-link PHYs registered using of_phy_register_fixed_link(). Convert the two drivers that care to deregister their fixed-link PHYs to use the new helper, but note that most drivers currently fail to do so.

NAND:
* Add the infrastructure to automate NAND timings configuration
* Provide a generic DT property to maximize ECC strength
* Some refactoring in the core bad block table handling, to help with
improving some of the logic in error cases.
* Minor cleanups and fixes
MTD:
* Add APIs for handling page pairing; this is necessary for reliably
supporting MLC and TLC NAND flash, where paired-page disturbance affects
reliability. Upper layers (e.g., UBI) should make use of these in the near
future.

console: don't prefer first registered if DT specifies stdout-path
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.

having to do things like this:
dev->of_node ? &dev->of_node->fwnode : dev->fwnode
This seems unnecessary, when the OF code could instead simply fill in
the device's fwnode when binding the of_node, and let the drivers use
dev->fwnode either way. Let's give it a go and see what falls out.

of: Add array read functions with min/max size limits
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.

of: Make of_find_property_value_of_size take a length range
In preparation for adding variable-length array reads, change of_find_property_value_of_size so that it takes an optional maximum length. If the maximum is passed as 0, the behaviour is unchanged and it will return a property if it's >= the requested minimum length. If maximum is non-zero it will only return a property whose length is min <= l <= max.

of: fix reference counting in of_graph_get_endpoint_by_regs
The called of_graph_get_next_endpoint() already decrements the refcount
of the prev node, so it is wrong to do it again in the calling function.
Use the for_each_endpoint_of_node() helper to interate through the
endpoint OF nodes, which already does the right thing and simplifies
the code a bit.

FDT: Add a helper to get the subnode by given name
Sometimes it needs to check if there is a subnode of given node in FDT by given name. Introduce this helper to get the subnode if it exists.

of_mdio: select fixed phy support unconditionally
Calling the fixed-phy functions when CONFIG_FIXED_PHY=m as a previous
change tried cannot work if the caller is in built-in code:
drivers/of/built-in.o: In function `of_phy_register_fixed_link':
of_reserved_mem.c:(.text+0x85e0): undefined reference to `fixed_phy_register'
Making of_mdio depend on 'FIXED_PHY || !FIXED_PHY' would solve this
dependency by enforcing that OF_MDIO itself becomes a loadable module
when FIXED_PHY=y, but that creates a different dependency as it
breaks any built-in ethernet driver that uses of_mdio.
Making FIXED_PHY a bool option also cannot work, since it depends on
PHYLIB, which again is tristate.
This version now uses 'select FIXED_PHY' to ensure that the fixed-phy
portion of of_mdio is not optional. The main downside of this is
a small increase in code size for cases that do not need fixed phy
support, but it should avoid all of the link-time problems.

of/irq: Mark initialised interrupt controllers as populated
For interrupt controllers successfully initialised early via device-tree, mark these interrupt controllers as populated so we don't unnecessarily create a device and populate any platform data later on in the boot sequence when we populate all the various platform devices.

of: fix memory leak related to safe_name()
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:
unreferenced object 0xdf532e60 (size 32):
comm "swapper", pid 1, jiffies 4294892300 (age 1993.532s)

of/platform: Add common method to populate default bus
The arch code calls of_platform_populate() with default match table when it wants to populate default bus. This patch introduce a new of_platform_default_populate_init() and make it arch_initcall_sync(it should be later than some iommu configration, eg, of_iommu_init() and swiotlb_late_init in arm64), then we can finish above job in common method. In order to avoid the default bus being populated twice, simply checking the flag of bus node whether has be set OF_POPULATED_BUS or not. After that, we can safely remove the caller in arch code. Btw, add debug print in of_platform_populate(), and use __func__ to print function's name of of_platform_bus_create().
