Implement a nice generalization suggested by Bobby Noelte.
Instead of having a generic #cells key in bindings, have source-specific
*-cells keys. Some examples:
interrupt-cells:
- irq
- priority
- flags
gpio-cells:
- pin
- flags
pwm-cells:
- channel
- period
This makes bindings a bit easier to read, and allows a node to be a
controller for many different 'phandle-array' properties.
The prefix before *-cells is derived from the property name, meaning
there's no fixed set of *-cells keys. This is possible because of the
earlier 'phandle-array' generalization.
The older #cells key is supported for backwards compatibility, but
generates a deprecation warning.

Fix handling of parentheses in macro argument values

Generating generic information for 'type: phandle-array' properties in
edtlib was difficult due to defining phandle-array as just a list of
phandles and numbers. To make sense of a phandle-array property like
'pwms', you have to know that #pwm-cells is expected to appear on
each referenced controller, and that the binding for the controller has
a #cells.
Because of this, handling of various 'type: phandle-array' properties
was previously hardcoded in edtlib and exposed through properties like
Node.pwms, instead of through the generic Node.props (though with a lot
of shared code).
In practice, it turns out that all 'type: phandle-array' properties in
Zephyr work exactly the same way: They all have names that end in -s,
the 's' is removed to derive the name of related properties, and they
all look up #cells in the binding for the controller, which gives names
to the data values.
Strengthen the definition of 'type: phandle-array' to mean a property
that works exactly like the existing phandle-array properties (which
also means requiring that the name ends in -s). This removes a ton of
hardcoding from edtlib and allows new 'type: phandle-array' properties
to be added without making any code changes.
If we ever need a property type that's a list of phandles and numbers
but that doesn't follow this scheme, then we could add a separate type
for it. We should check if the standard scheme is fine first though.
The only property type for which no information is generated is now
'compound'.
There's some inconsistency in how we generate identifiers for clocks
compared to other 'type: phandle-array' properties, so keep
special-casing them for now in gen_defines.py (see the comment in
write_clocks()).
This change also enabled a bunch of other simplifications, like reusing
the ControllerAndData class for interrupts.
Piggyback generalization of *-map properties so that they work for any
phandle-array properties. It's now possible to have things like
'io-channel-map', if you need to.

edtlib.Device is just a devicetree node augmented with binding

flash partition nodes "devices", which is a bit confusing.
I called it edtlib.Device instead of edtlib.Node originally to avoid
confusion with dtlib.Node, but in retrospect it probably makes it more
confusing on the whole. Something like edtlib.ENode might work too, but
it's probably overkill. Clients of edtlib.py only interact with
edtlib.Node, so the only potential for confusion is within edtlib.py
itself, and it doesn't get too bad there either.

As a slightly hairy but important optimization inherited from the old
scripts, the binding loading code only looks at binding files whose raw
text contains one of the compatible strings from the devicetree. For
such files, a second pass parses the file as YAML and tries to extract a
compatible string, and skips the file if it fails (e.g. due to spurious
text matches in 'include'd binding fragments).
Until now, the binding would always get fully loaded (have 'include'd
files merged in, checks run, etc.) if the second pass managed to extract
a compatible.
Do slightly better by only fully loading the binding if the extracted
compatible from the second pass appears in the devicetree. This gets rid
of unnecessary binding loading in rare cases.
Discovered by test-bindings/deprecated.yaml getting loaded even when
everything that referenced it in test.dts was commented out, because it
happened to mention 'child-binding' in a comment.
Also add a check for YAML errors in the second pass, to be slightly more
robust. Print a warning if a file that isn't valid YAML is found.

API oversight. This was meant to be there all along together with
Device.parent, for navigating the devicetree, but since a need for it
never came up in gen_defines.py, it got overlooked.
Devices are just devicetree nodes augmented with binding information and
some interpretation of devicetree properties. I wonder if the name
should be changed to something like edtlib.Node to make that clearer.
Calling something like a flash partition a "device" is a bit weird, as
Galak pointed out.
I think I went with Device originally to avoid confusion with
dtlib.Node, but since edtlib users don't directly interact with dtlib,
it might not be that confusing in practice.

Deprecate 'sub-node:' and add a more general 'child-binding:' mechanism
to bindings. Keep supporting 'sub-node:', but print a deprecation
warning when it's used.
Like 'sub-node:', 'child-binding:' gives a binding to child nodes, but
the binding is required to be a complete binding, and is treated (and
checked) like a normal binding.
'child-binding:' can in turn contain another 'child-binding:', up to any
number of levels. This is automatic from treating it like a normal
binding, and from the code initializing parent Devices before child
Devices.
This lets nodes give bindings to grandchildren.
For example, take this devicetree fragment:
parent {
compatible = "foo";
child-1 {
grandchild-1 {
...
};
grandchild-2 {
...
};
};
child-2 {
grandchild-3 {
...
};
};
};
The binding for 'foo' could provide bindings for grandchild-1/2/3 like
this:
compatible: "foo"
# Binding for children
child-binding:
title: ...
description: ...
...
# Binding for grandchildren
child-binding:
title: ...
description: ...
properties:
...
Due to implementation issues with the old devicetree scripts, only two
levels of 'child-binding:' is supported for now. This limitation will go
away in Zephyr 2.2.
Piggyback shortening 'description:' and 'title:' in some bindings that
provide child bindings. This makes the generated header a bit neater.

Currently, string values comming from "common" test definition section
and from test-specific section are just concatenated. Suppose, we want
to define some common filter condition, and also per-test additional

common:
filter: TOOLCHAIN_FOO == 1
tests:
sample.net.sockets.http_get.posix:
filter: and not CONFIG_BAR
That's arguable quite adhoc, and the only way to figure it out for

System call arguments, at the arch layer, are single words. So
passing wider values requires splitting them into two registers at
call time. This gets even more complicated for values (e.g
k_timeout_t) that may have different sizes depending on configuration.
This patch adds a feature to gen_syscalls.py to detect functions with
wide arguments and automatically generates code to split/unsplit them.
Unfortunately the current scheme of Z_SYSCALL_DECLARE_* macros won't
work with functions like this, because for N arguments (our current
maximum N is 10) there are 2^N possible configurations of argument
widths. So this generates the complete functions for each handler and
wrapper, effectively doing in python what was originally done in the
preprocessor.
Another complexity is that traditional the z_hdlr_*() function for a
system call has taken the raw list of word arguments, which does not
work when some of those arguments must be 64 bit types. So instead of
using a single Z_SYSCALL_HANDLER macro, this splits the job of
z_hdlr_*() into two steps: An automatically-generated unmarshalling
function, z_mrsh_*(), which then calls a user-supplied verification
function z_vrfy_*(). The verification function is typesafe, and is a
simple C function with exactly the same argument and return signature
as the syscall impl function. It is also not responsible for
validating the pointers to the extra parameter array or a wide return
value, that code gets automatically generated.
This commit includes new vrfy/msrh handling for all syscalls invoked
during CI runs. Future commits will port the less testable code.

When foo.yaml set some property 'required: true' and bar.yaml set the

The order files are included in shouldn't matter. To fix it, change the

'required' true-to-false check when merging included files.
