4c29e5934f microblaze: get cpu node with of_get_cpu_node
"device_type" use is deprecated for FDT though it has continued to be used
for nodes like cpu nodes. Use of_get_cpu_node() instead which works using
node names by default. This will allow the eventually removal of cpu
device_type properties.

Also, fix a leaked reference by adding a missing of_node_put.

f1f207e43b of: Add cpu node iterator for_each_of_cpu_node()
Iterating thru cpu nodes is a common pattern. Create a common iterator
which can find child nodes either by node name or device_type == cpu.
Using the former will allow for eventually dropping device_type
properties which are deprecated for FDT.

da08d8cb8c of: unittest: Disable interrupt node tests for old world MAC systems
On systems with OF_IMAP_OLDWORLD_MAC set in of_irq_workarounds, the
devicetree interrupt parsing code is different, causing unit tests of
devicetree interrupt nodes to fail. Due to a bug in unittest code, which
tries to dereference an uninitialized pointer, this results in a crash.

The problem was observed when running a qemu test for the g3beige machine
with devicetree unittests enabled.

Disable interrupt node tests on affected systems to avoid both false
unittest failures and the crash.

With this patch in place, unittest on the affected system passes with
the following message.

29e5f9441b dt-binding: arm/cpus.txt: fix dynamic-power-coefficient unit
The unit of dynamic-power-coefficient is described as mW/MHz/uV^2 whereas
its usage in the code assumes that unit is uW/MHz/V^2

In drivers/thermal/cpu_cooling.c, the code is :

power = (u64)capacitance * freq_mhz * voltage_mv * voltage_mv;
do_div(power, 1000000000);

which can be summarized as :
power (mW) = capacitance * freq_mhz/1000 * (voltage_mv/1000)^2
or
power (mW) = (capacitance * freq_mhz * (voltage_mv/1000)^2) / 1000
then
power (mW) = power (uW) / 1000
so
power (uW) = capacitance * freq_mhz * (voltage_mv/1000)^2

Furthermore, if we test basic values like :
voltage_mv = 1000mV = 1V
freq_mhz = 1000Mhz

The minimum possible power, when dynamic-power-coefficient equals 1, will
be with current unit:
min power = 1 * 1000  * (1000000)^2 = 10^15 mW
which is not realistic

With the unit used by the code, the min power is
min power =  1 * 1000 * 1^2 = 1000uW = 1mW which is far more realistic

f858927fd6 scripts/dtc: Update to upstream version v1.4.7-14-gc86da84d30e4
Major changes are I2C and SPI bus checks, YAML output format (for
future validation), some new libfdt functions, and more libfdt
validation of dtbs.

The YAML addition adds an optional dependency on libyaml. pkg-config is
used to test for it and pkg-config became a kconfig dependency in 4.18.

This adds the following commits from upstream:

e54192b48d of: fix phandle cache creation for DTs with no phandles
With commit 0b3ce78e90 ("of: cache phandle nodes to reduce cost of
of_find_node_by_phandle()"), a G3 PowerMac fails to boot. The root cause
is the DT for this system has no phandle properties when booted with
BootX. of_populate_phandle_cache() does not handle the case of no
phandles correctly. The problem is roundup_pow_of_two() for 0 is
undefined. The implementation subtracts 1 underflowing and then things
are in the weeds.

00b7d1cf46 of: make default address and size cells sizes private
Only some old OpenFirmware implementations rely on default sizes. Any
FDT and modern implementation should have explicit properties. Make the
OF_ROOT_NODE_*_CELLS_DEFAULT defines private so we don't get any outside
users.

This also gets us one step closer to removing the asm/prom.h dependency on
Sparc.

b610e2ff46 of/unittest: remove use of node name pointer in overlay high level test
In preparation for removing the node name pointer, it needs to be
removed from of_unittest_overlay_high_level. However, it's not really
correct to use the node name without the unit-address and we should use
the full node name. This most easily done by iterating over the child
nodes with for_each_child_of_node() which is what of_get_child_by_name()
does internally. While at it, we might as well convert the outer loop to
use for_each_child_of_node() too instead of open coding it.
