9df9994572 x86: fix XIP SOC support and defaults
XIP support in x86 was something of a mess. This
patch does the following:

- Generic ia32 SOC no longer defines a "flash" region
  as generic X86 devices don't have a microcontroller-
  like concept of flash. The same has been done for apollo_lake.
- Generic ia32 and apollo_lake SOCs starts memory at 1MB.
- Generic ia32 SOC may optionally have CONFIG_XIP enabled.
  The board definition must provide a flash region definition
  that gets exposed as DT_PHYS_LOAD_ADDR.
- Fixed definitions for RAM/ROM source addresses in ia32's
  linker.ld when XIP is turned off.
- Support for enabling XIP on apollo_lake SOC removed, there's
  no use-case.
- acrn and gpmrb boards have flash and XIP related definitions
  removed.
- qemu_x86 has a fake flash region added, immediately after system
  RAM, for use when XIP is enabled. This used to be in the ia32 SOC.
  However, the default for qemu_x86 is to now have XIP disabled.
- Fixed tests/kernel/xip to run by default on boards that enable
  XIP by default, plus an additional test to exercise XIP on
  qemu_x86 (which supports it but has XIP switched off by default)

The overall effect of this patch is to:

- Remove XIP configuration for SOC/boards where it does not make
  any sense to have it
- Support testing XIP on qemu_x86 via tests/kernel/xip, but leave
  it off by default for other tests, to ensure it doesn't bit-rot
  and that the system works in both scenarios.
- XIP remains an available feature for boards that need it.

2845d8f404 scripts: edtlib: Make order irrelevant when including multiple files
When foo.yaml set some property 'required: true' and bar.yaml set the
same property 'required: false', the check for changing
'required: false' to 'required: true' would raise an error for

    include: [bar.yaml, foo.yaml]

(with that particular order due to implementation details).

The order files are included in shouldn't matter. To fix it, change the
logic so that 'required' values are ORed together between included files
(so that 'required: true' is always respected), and remove the
'required' true-to-false check when merging included files.

Keep the true-to-false check when merging the (merged) included files
into the main binding (the binding with the 'include:' in it). This
might give a good organization, and the old scripts do it too.

Piggyback two fixes/cleanups:

 - 'compatible' should be allowed to appear in included files

 - No need to allow an 'inherits' key in _check_binding(), because
   it has been removed before then, when merging bindings

2d035c4191 drivers: esp32: Add UART Driver with FIFO/Interrupt support
- Fixes #3981
- Implement UART Polling functions
- Implement UART Interrupt APIs
- Remove dependency on esp32_rom_uart_xxx functions
- Update Device tree with UART addresses and pin config
- Update ESP32 UART KConfig

Notes about implementation:
- Interrupts now defined as a local macros, and should be removed
later on, when interrupts for esp32 are supported in dts

- Threshold interrupts are used for TX/RX
- Reseting FIFOs using _RST bit will corrupt FIFO of UART2 when used for
UART1 and vice-versa, so a generic way is used for all three UARTs

- Old Silicon rev is not supported

a19356d79b dts: nordic: nrf9160: Add missing peripheral nodes
For quite a few peripherals that are currently supported by nrfx HALs
or drivers there are no definitions of corresponding CMSIS-Core
peripheral accessing symbols that would provide their base addresses
in the proper domain (secure or non-secure), accordingly to the build
target. This commits adds devicetree nodes for these peripherals so
that their base addresses can be used in definitions of the accessing
symbols mentioned above.

80433e218a dts: rv32m1: Rework interrupt mux dts descriptions
Each intmux block acts like 8 interrupt controllers in which we can
have multiple device interrupts on a single channel and that channel
than interrupt than chained to another interrupt controller (in the
case of the RISC-V cores, it is the event unit).

So to describe things better to properly be able to walk the interrupt
chain in the device tree we treat each channel in the interrupt mux as
an interrupt controller rather than the intmux as a single interrupt
controller.

In the future this will allow the device tree generation code to walk
the interrupt chain from the device and up through any interrupt
controllers to generate the IRQ value that Zephyr expects (rather than
us hard coding this into the DTS).

ff1f75293e dts: edtlib: Support giving missing properties a default value
For missing optional properties, it can be handy to generate a default
value instead of no value, to cut down on #ifdefs.

Allow a default value to be specified in the binding, via a new
'default: <default value>' setting for properties in bindings.
Defaults are supported for both scalar and array types. YAML arrays are
used to specify the value for array types.

'default:' also appears in json-schema, with the same meaning.

Include misc. sanity checks, like the 'default' value matching 'type'.

The documentation changes in binding-template.yaml explain the syntax.

a0fceff1a2 scripts: dts: Simplify and improve 'compatible' matching
Instead of

    properties:
        compatible:
            constraint: "foo"

, just have

    compatible: "foo"

at the top level of the binding.

For backwards compatibility, the old 'properties: compatible: ...' form
is still accepted for now, and is treated the same as a single-element
'compatible:'.

The old syntax was inspired by dt-schema (though it isn't
dt-schema-compatible), which is in turn a thin wrapper around
json-schema (the idea is to transform .dts files into YAML and then
verify them).

Maybe the idea was to gradually switch the syntax over to dt-schema and
then be able to use unmodified dt-schema bindings, but dt-schema is
really a different kind of tool (a completely standalone linter), and
works very differently from our stuff (see schemas/dt-core.yaml in the
dt-schema repo to get an idea of just how differently).

Better to keep it simple.

This commit also piggybacks some clarifications to the binding template
re. '#cells:'.

d834b69bd9 scripts: dts: Improve syntax and code for including binding files
Have

    include: foo.dts
    include: [foo.dts, bar.dts]

instead of

    inherits:
        !include foo.dts

    inherits:
        !include [foo.dts, bar.dts]

This is a nicer and shorter and less cryptic syntax, and will make it
possible to get rid of the custom PyYAML constructor for '!include'
later.

'inherits: !include ...' is still supported for backwards compatibility
for now. Later on, I'm planning to mass-replace it, add a deprecation
warning if it's used, and document 'include:'. Then the '!include'
implementation can be removed a bit later.

'!include' has caused issues in the past (see the comment above the
add_constructor() call), gets iffy with multiple EDT instances, and
makes the code harder to follow.

I'm guessing '!include' might've been intended to be useful outside of
'inherits:' originally, but that's the only place where it's used. It's
undocumented that it's possible to put it elsewhere.

To implement the backwards compatibility, the code just transforms

    inherits:
        !include foo.dts

into

    inherits:
        - foo.dts

and treats 'inherits:' similarly to 'include:'. Previously, !include
inserted the contents of the included file instead.

Some more sanity checks for 'include:'/'inherits:' are included as well.

fcd665a26c dts: bindings: Have 'required: true/false' instead of 'category: ...'
The 'category: required/optional' setting for properties is just a
yes/no thing. Using a boolean makes it clearer, so have
'required: true/false' instead.

Print a clear error when 'category:' is used:

    edtlib.EDTError: please put 'required: true' instead of 'category:
    required' in 'properties: foo: ...' in
    test-bindings/sub-node-parent.yaml - 'category' has been removed

The old scripts in scripts/dts/ ignore this setting, and only print a
warning if 'category: required' in an inherited binding is changed to
'category: optional'. Remove that code, since the new scripts already
have the same check.

The replacement was done with

    git ls-files 'dts/bindings/*.yaml' | xargs sed -i \
        -e 's/category:\s*required/required: true/' \
        -e 's/category:\s*optional/required: false/'

1480ad9ce7 dts: edtlib: Sanity-check the final merged binding only
Sanity-checking each !included file separately was inherited from the
old scripts. It makes it messy to check that combinations of fields make
sense, e.g. to check 'const:' or 'default:' against 'type:', since those
fields might come from different files (this is handy, since it makes
sense to just add/change a 'const:' value, for example).

Drop the requirement that each !included file is a complete binding in
itself, and treat them as binding fragments instead. Only check the
final merged binding.

This also means that !included files no longer need to have a
'description:' or 'title:' (those have always been unused for !included
files), so remove those, and add comments that explain what the
fragments are for instead. That should demystify bindings a bit.

Also fix the descriptions of i2c.yaml, i2s.yaml, spi.yaml, and
uart.yaml. They're for controllers, not devices. These are copy-paste
error from the corresponding device .yaml files.

Piggyback some indentation consistency nits in binding-template.yaml.

c42873fbe7 dts: dtlib/edtlib: Add phandle and phandle+nums array types
Add two new type-checked property types 'phandles' and 'phandle-array'
to edtlib.

'phandles' is for pure lists of phandles, with no other data, like

    foo = < &bar &baz ... >

'phandle-array' is for lists of phandles and (possibly) numbers, like

    foo = < &bar 1 2 &baz 3 4 ... >

dt-schema also has the 'phandle-array' type.

Property.val (in edtlib) is set to an array of Device objects for the
'phandles' type.

For the 'phandle-array' type, no Property object is created. This type
is only used for type checking.

Also refactor how types that do not create a Property object
('phandle-array' and 'compound') are handled. Have _prop_val() return
None for them.

The new types are implemented with two new TYPE_PHANDLES and
TYPE_PHANDLES_AND_NUMS types at the dtlib level. There is also a new
Property.to_nodes() functions for fetching the Nodes for an array of
phandles, with type checking.

* Add "interrupt-extended" to base.yaml.  Provides a way to specify
  an interrupt-parent and specifier in a single property.  Useful if
  a device has multiple interrupts in which different interrupts go
  to different interrult controllers.

b012034519 dts/bindings: use const to validate #<FOO>-cells
In most cases #<FOO>-cells should be a constant.  For example in spi
controller #address-cells should be 1, and #size-cells should be 0.

Use the const attribute to specify such single known values.  Add const
value to missing bindings which have cells.

3d14374c5e scripts/dts/edtlib.py: add 'const' support to bindings
Add a 'const' property to bindings for any properties that are expected
to have a specifi known value.  For example, #address-cells for an I2C
bus should always be '1'.  So we can do something like the following in
the I2C bus binding:

    "#address-cells":
      type: int
      category: required
      const: 1

2db8518c9d dts/binding/sensor: Fix ST sensors irq-gpios property being required
Change binding for ST sensors property 'irq-gpios' to optional for the
cases of in which its obvious from the driver that the property is
optional (there's an ifdef based on the #define
DT_INST_0_ST_LIS2DH_IRQ_GPIOS_*).

'child: bus:' should be in the binding for the bus node, and
'parent: bus:' in the binding for devices that appear on the bus.

The description accidentally swapped them. Fix it.

f38e27603d dts: xilinx_zynqmp: Remove stray 0 from interrupt-parent
'interrupt-parent' should contain just the phandle of the node
interrupts are sent to.

This node (gic: interrupt-controller@f9010000) doesn't generate any
interrupts, so the 'interrupt-parent' value is never used (this is why
it wasn't caught). It'll give an error later with 'interrupt-parent'
declared as 'type: phandle' in bindings though.

Don't know what was intended. Just remove the 0.
