Masahiro Yamada 5c68b8231e of/fdt: pass early_init_dt_reserve_memory_arch() with bool type nomap
The third argument 'nomap' of early_init_dt_reserve_memory_arch() is
bool. It is preferred to pass it with a bool type parameter.

There is no need to cast "u64" to "unsigned long long" before printing

Maxime Ripard 67d0da9916 dt-bindings: net: Use phy-mode instead of phy-connection-type
When adding support for the DWMAC (and derivatives) bindings,
phy-connection-type was required, even though the previous binding required
the equivalent phy-mode.

Let's fix this by using phy-mode as we should have.

Both the allwinner and amlogic compatibles require that either the
allwinner,pipeline or the amlogic,pipeline property is set. This was
dropped during the conversion since we didn't have conditionals back then,

Rob Herring 9ea6b821ce dt-bindings: arm: Limit cpus schema to only check Arm 'cpu' nodes
Matching on the 'cpus' node was a bad choice because the schema is
incorrectly applied to non-Arm cpus nodes. As we now have a common cpus
schema which checks the general structure, it is also redundant to do so
in the Arm CPU schema.

The downside is one could conceivably mix different architecture's cpu
nodes or have typos in the compatible string. The latter problem pretty
much exists for every schema.

Brian Masney ef4db28c1f dt-bindings: backlight: lm3630a: correct schema validation
The '#address-cells' and '#size-cells' properties were not defined in
the lm3630a bindings and would cause the following error when
attempting to validate the examples against the schema:

Documentation/devicetree/bindings/leds/backlight/lm3630a-backlight.example.dt.yaml:
'#address-cells', '#size-cells' do not match any of the regexes:
'^led@[01]$', 'pinctrl-[0-9]+'

Correct this by adding those two properties.

While we're here, move the ti,linear-mapping-mode property to the
led@[01] child nodes to correct the following validation error:

Stephen Boyd 7c71650f9a of/fdt: Mark initial_boot_params as __ro_after_init
The FDT pointer, i.e. initial_boot_params, shouldn't be changed after
init. It's only set by boot code and then the only user of the FDT is
the raw sysfs reading API. Mark this pointer with __ro_after_init so
that the pointer can't be changed after init.

Stephen Boyd 9b4d2b635b of/fdt: Remove dead code and mark functions with __init
Some functions in here are never called, and others are only called
during __init. Remove the dead code and some dead exports for functions
that don't exist (I'm looking at you of_fdt_get_string!). Mark some
functions with __init so we can throw them away after we boot up and
poke at the FDT blob too.

Stephen Boyd 253a41c6fb dt-bindings: Remove Linuxisms from common-properties binding
We shouldn't reference Linux kernel functions or Linux itself in proper
bindings. It's OK to reference functions in the kernel when explaining
examples, but otherwise we shouldn't reference functions to describe
what the binding means.

Krishna Reddy d698a38814 of: reserved-memory: ignore disabled memory-region nodes
Ignore disabled nodes in the memory-region
nodes list and continue to initialize the rest
of enabled nodes.

Check if the "reserved-memory" node is available
and if it's not available, return 0 to ignore the
"reserved-memory" node and continue parsing with
next node in memory-region nodes list.

Add Espressif Systems DT vendor prefix. That prefix has been used for quite
