Maureen Helm ca43b7ceb4 dts: Add bindings for ft5336 touch panel controller
Adds device tree bindings for the focaltech ft5336 touch panel
controller, which will be used on several i.mx rt evk boards.

Moves address-cells and size-cells properties from the base kscan
bindings to the specific microchip,xec bindings since they are not

Carlo Caione 6f36300219 drivers: timer: Add per-core ARM architected timer
ARM cores may have a per-core architected timer, which provides per-cpu
timers, attached to a GIC to deliver its per-processor interrupts via
PPIs. This is the most common case supported by QEMU in the virt
platform.

This patch introduces support for this timer abstracting the way the
timer registers are actually accessed. This is needed because different
architectures (for example ARMv7-R vs ARMv8-A) use different registers
and even the same architecture (ARMv8-A) can actually use different
timers (ELx physical timers vs ELx virtual timers).

So we introduce the common driver here but the actual SoC / architecture
/ board must provide the three helpers (arm_arch_timer_set_compare(),
arm_arch_timer_toggle(), arm_arch_timer_count()) using an header file
imported through the arch/cpu.h header file.

Kamil Lazowski 5b4f4253c1 drivers: flash: add Nordic JEDEC QSPI NOR flash driver
Most JEDEC NOR flash devices uses not only typical SPI mode
(MISO,MOSI,SCK and CS), but also QSPI mode (IO0,IO1,IO2,IO3,SCK and CS).
QSPI mode uses more data lines and as a result provide higher
throughput. If this were not enough, Nordic chips provide
hardware acceleration for read/write/erase functions, what
gives significant performance boost.
It does a lot of things "behind the scene", i.e when user has written
some data to the flash and would like to read them back, it has to wait
until the flash is ready by reading WIP bit in Status Register.
This driver does it automatically.

Peter Bigot bb106390a2 dts: bindings: generalize JEDEC SPI NOR descriptions
Currently most SPI NOR serial flash devices are accessed through the
spi-nor flash driver, but there are pending enhancements that will
access these devices through other driver implementations.  Several of
the descriptive properties of the flash memories are common regardless
of the interface selected.  Pull those out to a separate yaml file to
be included into the bindings for interface-specific node descriptions.

Also revise the documentation to note that the jedec,spi-nor
compatible depends on a commands set compatible with the Micron M25P80
serial nor flash; there is no JEDEC standard for these commands.
These devices do generally provide descriptive structures defined by
JESD216, but currently Zephyr doesn't make use of these structures.
The JEDEC CFI standard previously referenced in the description is not
relevant to these devices.

Carlo Caione 7baf3f74a9 interrupt_controller: gic: Support PPIs
The GIC-400 driver currently only supports SPIs because the (32) offset
for the INTIDs is hard-coded in the driver. At the driver level there is
no really difference between PPIs and SPIs so we can easily extend the
driver to support PPIs as well.

This is useful if we want to add support for the ARM Generic Timers that
use INTIDs in the PPI range.

SPI interrupts are in the range [0-987]. PPI interrupts are in the range
[0-15].

This commit adds interrupt 'type' cell to the GIC device tree binding
and changes the 'irq' cell to use interrupt type-specific index, rather
than a linear IRQ number.

The 'type'+'irq (index)' combo is automatically fixed up into a linear
IRQ number by the scripts/dts/gen_defines.py script.

Andrzej Głąbek 69c75c7267 drivers: spi: nrfx: Move MISO lines pull configuration to DT
After switching to nrfx 2.0.0, the Kconfig choice options that allowed
enabling of pull-up or pull-down for MISO lines in SPIs and SPIMs are
not properly supported, they are simply ignored. This commit restores
the possibility of applying pull configuration for MISO lines.

In earlier nrfx versions, the MISO pull configuration could be only
set globally, in nrfx_config files, for all SPI and SPIM instances
together. Since nrfx 2.0.0, this configuration can be applied per
instance. This commit takes advantage of this possibility and instead
of using a common Kconfig option as a global setting for all instances,
allows applying individual instance settings via devicetree.

Ulf Magnusson b9240a3cbc dts: bindings: Preserve newlines in descriptions
With https://github.com/zephyrproject-rtos/zephyr/pull/20185, multi-line
descriptions will be formatted nicely, but using '>' breaks it, because
it removes internal newlines (including between paragraphs).

See https://yaml-multiline.info/.

Replace 'description: >' with 'description: |' to encourage '|'. That'll
prevent '>' from getting copied around and messing up long descriptions.

This will lead to some extra newlines in the output, but it's fine.
Line-wrapping messes up any manual formatting.

The replacement was done with

mistake. Combining 'type: boolean' with 'required: true' for 'ppi-wrap'
means that all nodes that use this binding are required to have a
'ppi-wrap;' property.

The mistake was hidden by a bug in edtlib (failing to flag missing
'required: true' booleans).

Ulf Magnusson 567c348167 scripts: dts: Generalize '#cells' to allow multiple sources
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.

Ulf Magnusson b97ed9e4b4 scripts: dts: Generalize handling of phandle-array types
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.

Andrzej Głąbek f43bae38e8 dts: Use separate compatibles for Nordic SPI/SPIM/SPIS peripherals
This commit introduces separate "compatible" strings for DTS nodes
representing different types of Nordic SPI peripherals. Previously
"nordic,nrf-spi" was used for both SPI and SPIM. SPIS was already
handled separately.

Quite a few files need to be touched by this commit but the changes can
be divided into groups of related or very similar ones, distinguishable
by the initial part of the path to the modified file:

* dts/bindings/spi/
  new binding for "nordic,nrf-spim" is added and common fields for all
  3 types of Nordic SPI peripherals are extracted to a shared file

* dts/arm/nordic/
  "compatible" properties in spiX nodes are updated (when there is no
  choice as only one type of SPI peripheral is available) or replaced
  with a comment pointing out that the proper type of peripheral needs
  to be picked at some upper layer

* drivers/spi/
  spi_nrfx_spim driver is updated with the new form of macros generated
  from dts

* boards/

  updated with the proper "compatible" property, according to the type
  of SPI peripheral that is currently selected for the board by the
  corresponding Kconfig choice option (SPI_x_NRF_SPI*)

Ulf Magnusson 0b1ab4ab09 scripts: dts: Replace 'sub-node:' with more general 'child-binding:'
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.

Kumar Gala 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).

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

'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/'

Ulf Magnusson 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.

Ulf Magnusson 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.

Ulf Magnusson 06b746cc58 dts: dtlib/edtlib: Add a syntax-based type-checking system
Property type-checking has been pretty rudimentary until now, only
checking things like the length being divisible by 4 for 'type: array',
and strings being null-terminated. In particular, no checking was done
for 'type: uint8-array', letting

  jedec-id = < 0xc8 0x28 0x17 >;

slip through when

  jedec-id = [ 0xc8 0x28 0x17 ];

was intended.

Fix it by adding a syntax-based type checker:

  1. Add Property.type, which gives a high-level type for the property,
     derived from the markers added in the previous commit.

     This includes types like TYPE_EMPTY ('foo;'),
     TYPE_NUM ('foo = < 3 >;'), TYPE_BYTES ('foo = [ 01 02 ];'),
     TYPE_STRINGS ('foo = "bar", "baz"'),
     TYPE_PHANDLE ('foo = < &bar >;'), and TYPE_COMPOUND (everything not
     recognized).

     See the Property.type docstring in dtlib for more info.

  2. Use the high-level type in
     Property.to_num()/to_string()/to_node()/etc. to verify that the
     property was assigned in an expected way for the type.

     If the assignment looks bad, give a helpful error:

       expected property 'nums' on /foo/bar in some.dts to be assigned
       with 'nums = < (number) (number) ... >', not 'nums = "oops";'

Some other related changes are included as well:

  - There's a new Property.to_bytes() function that works like accessing
    Property.bytes, except with an added check for the value being
    assigned like 'foo = [ ... ]'.

    This function solves problems like the jedec-id one.

  - There's a new Property.to_path() function for fetching the
    referenced node for assignments like 'foo = &node;', with type
    checking. (Strings are accepted too, as long as they give the path
    to an existing node.)

    This function is used for /chosen and /aliases.

  - A new 'type: phandle' type can now be given in bindings, for
    properties that are assigned like 'foo = < &node >;'.

  - Property.__str__() now displays phandles and path references as they
    were written (e.g. '< &foo >' instead of '< 0x1 >', if the
    allocated phandle happened to be 1).

  - Property.to_num() and Property.to_nums() no longer take a 'length'
    parameter, because it makes no sense with the type checking.

  - The global dtlib.to_string() and dtlib.to_strings() functions were
    removed, because they're not that useful.

  - More tests were added, along with misc. minor cleanup in various
    places.

  - Probably other stuff I forgot.

The more strict type checking in dtlib indirectly makes some parts of
edtlib more strict as well (wherever Property.to_*() is used).

Add a new sifive,plic-1.0.0 binding that inherits from the riscv,plic0
binding. The new binding adds a required riscv,ndev property, which
gives the number of external interrupts supported.

Use the new binding for microsemi-miv.dtsi (with a value of 31 for
riscv,ndev, from http://www.actel.com/ipdocs/MiV_RV32IMAF_L1_AHB_HB.pdf)
and riscv32-fe310.dtsi (which already assigns riscv,ndev).

Scott Worley bdaab8cfa0 drivers : timer : Add MEC1501 32KHz kernel timer driver
Add a kernel timer driver for the MEC1501 32KHz RTOS timer.
This timer is a count down 32-bit counter clocked at a fixed
32768 Hz. It features one-shot, auto-reload, and halt count down
while the Cortex-M is halted by JTAG/SWD. This driver is based
on the new Intel local APIC driver. The driver was tuned for
accuracy at small sleep values. Added a work-around for RTOS
timer restart issue. RTOS timer driver requires board ticks per
second to be 32768 if tickless operation is configured.

Ulf Magnusson 0ec0c84808 dts: bindings: Remove unused 'version' field
No binding has anything but 'version: 0.1', and the code in scripts/dts/
never does anything with it except print a warning if it isn't there.
It's undocumented what it means.

I suspect it's overkill if it's meant to be the binding format version.
If we'd need to tell different versions from each other, we could change
some other minor thing in the format, and it probably won't be needed.

Remove the 'version' fields from the bindings and the warning from the
scripts/dts/ scripts.

The new device tree script will give an error when unknown fields appear
in bindings.

The deletion was done with

    git ls-files 'dts/bindings/*.yaml' | xargs sed -i '/^\s*version: /d'

Some blank lines at the beginning of bindings were removed as well.
