cfe4d51b4f drivers: sensor: Add adc-comparator binding and implementation for NPCX
Comparator will monitor signal though ADC channel, based on
user configuration, callback will be triggered.
This will enable comparator functionality for nuvoton MCU utilizing its
ADC threshold detection feature. Implementation is exported through
sensor trigger API. Use of CONFIG_ADC_CMP_NPCX is required.

586e26e8fc soc: nrf: Use data from DTS to populate HAS_HW_NRF_* Kconfig options
Instead of selecting appropriate HAS_HW_NRF_* options for particular
nRF SoCs (and simulated nRF52 target), set their values basing on
information from devicetree.
Correct also semantics of those options so that they are set only when
a corresponding DT node is enabled. This allows using them directly in
Kconfig dependencies of Zephyr drivers for nRF peripherals. Update
appropriately these dependencies.

8a4013b2e1 drivers: adc: Set correct interrupt type and remove spurious interrupts
In npcx adc driver, we select 'Scan' (Multiple Channels Operation Mode)
mode by default. It means that selected channels in ADCCS will be
converted automatically. Then, read the measured data from CHNDAT
registers if EOCCEV (Event is set after all selected channels are
converted.) flag in ADCSTS is set.

But we enable the wrong interrupt type, INTECEN, during adc
initialization. Ec will send the interrupt after each channel in ADCCS
is converted. It has no harm to the current driver since the driver
reads all selected channels and turns off ADC converter only after
EOCCEV is set in ISR. But it does generate spurious interrupts.

This CL enables the correct interrupt type, INTECCEN, during adc
initialization. Ec only sends the interrupt after all of channels in
ADCCS are converted.

4381841bd8 ITE: drivers/adc: fix the sampling flow of ADC
The ADC sampling of it8xxx2 needs to read each channel in sequence,
so it needs to wait for an interrupt to read data in the loop
through k_sem_take().

In test_adc.c, k_timer_start() is used in the interval test, so we
need to use polling wait instead of k_sem_take() to wait, otherwise
it will cause kernel panic.

k_is_in_isr() can determine whether to use polling or k_sem_take()
at present.

2c61c06a0e drivers/ADC: STM32: This solves coverity reported in ADC driver.
This commit it to resolve following bugs:
* Operands don't affect result.
* Logical dead code in stm32_adc driver.
Above mentioned bugs were solved by adding parenthesis and
changed the method of comparing. Since comparison of ADC
channel_id with the channel may cause loss of value.
So instead of direct comparison, introduced a mechanism to
convert channel constant to a decimal using
__LL_ADC_CHANNEL_TO_DECIMAL_NB() and strips away
the INTERNAL_CH bit and then compare with channel_id.

fix:

6e8775ff84 devicetree: remove DT_HAS_NODE_STATUS_OKAY
Several reviewers agreed that DT_HAS_NODE_STATUS_OKAY(...) was an
undesirable API for the following reasons:

- it's inconsistent with the rest of the DT_NODE_HAS_FOO names
- DT_NODE_HAS_FOO_BAR_BAZ(node) was agreed upon as a shorthand
  for macros which are equivalent to
  DT_NODE_HAS_FOO(node) && DT_NODE_HAS_BAR(node) &&
- DT_NODE_HAS_BAZ(node), and DT_HAS_NODE_STATUS_OKAY is an odd duck
- DT_NODE_HAS_STATUS(..., okay) was viewed as more readable anyway
- it is seen as a somewhat aesthetically challenged name

Replace all users with DT_NODE_HAS_STATUS(..., okay), which is
semantically equivalent.

This is mostly done with sed, but a few remaining cases were done by
hand, along with whitespace, docs, and comment changes. These special
cases include the Nordic SOC static assert files.

4f16b419e8 device: avoid casting away const from config_info pointer
The driver-specific config_info structure referenced from the device
structure is marked const.  Some drivers fail to preserve that
qualifier when casting the pointer to the driver-specific structure,
violating MISRA 11.8.

Changes produced by scripts/coccinelle/const_config_info.cocci.

Some changes proposed by the script are not included because they
reveal mutation of state through the const pointer, though the
code works as long as the driver-specific object is defined without
the const qualifier.

7e0eed9235 devicetree: allow access to all nodes
Usually, we want to operate only on "available" device
nodes ("available" means "status is okay and a matching binding is
found"), but that's not true in all cases.

Sometimes we want to operate on special nodes without matching
bindings, such as those describing memory.

To handle the distinction, change various additional devicetree APIs
making it clear that they operate only on available device nodes,
adjusting gen_defines and devicetree.h implementation details
accordingly:

- emit macros for all existing nodes in gen_defines.py, regardless
  of status or matching binding
- rename DT_NUM_INST to DT_NUM_INST_STATUS_OKAY
- rename DT_NODE_HAS_COMPAT to DT_NODE_HAS_COMPAT_STATUS_OKAY
- rename DT_INST_FOREACH to DT_INST_FOREACH_STATUS_OKAY
- rename DT_ANY_INST_ON_BUS to DT_ANY_INST_ON_BUS_STATUS_OKAY
- rewrite DT_HAS_NODE_STATUS_OKAY in terms of a new DT_NODE_HAS_STATUS
- resurrect DT_HAS_NODE in the form of DT_NODE_EXISTS
- remove DT_COMPAT_ON_BUS as a public API
- use the new default_prop_types edtlib parameter

87e1743ae0 devicetree: replace DT_HAS_DRV_INST with DT_INST_FOREACH
Make drivers multi-instance wherever possible using DT_INST_FOREACH.
This allows removing DT_HAS_DRV_INST in favor of making drivers just
do the right thing regardless of how many instances there are.

There are a few exceptions:

- SoC drivers which use CMake input files (like i2c_dw.c) or otherwise
  would require more time to convert than I have at the moment. For the
  sake of expediency, just inline the DT_HAS_DRV_INST expansion for
  now in these cases.

- SoC drivers which are explicitly single-instance (like the nRF SAADC
  driver). Again for the sake of expediency, drop a BUILD_ASSERT in
  those cases to make sure the assumption that all supported SoCs have
  at most one available instance is valid, failing fast otherwise.

32bb2395c2 timeout: Fix up API usage
Kernel timeouts have always been a 32 bit integer despite the
existence of generation macros, and existing code has been
inconsistent about using them.  Upcoming commits are going to make the
timeout arguments opaque, so fix things up to be rigorously correct.
Changes include:

+ Adding a K_TIMEOUT_EQ() macro for code that needs to compare timeout
  values for equality (e.g. with K_FOREVER or K_NO_WAIT).

+ Adding a k_msleep() synonym for k_sleep() which can continue to take
  integral arguments as k_sleep() moves away to timeout arguments.

+ Pervasively using the K_MSEC(), K_SECONDS(), et. al. macros to
  generate timeout arguments.

+ Removing the usage of K_NO_WAIT as the final argument to
  K_THREAD_DEFINE().  This is just a count of milliseconds and we need
  to use a zero.

This patch include no logic changes and should not affect generated
code at all.

b1d5eed262 drivers: nrfx: Update implementations after switching to nrfx 2.0.0
Update calls to nrfx HAL functions to reflect API changes introduced in
nrfx 2.0.0. All these functions are now called with the first parameter
pointing to the structure of registers of the relevant peripheral.
Also a few functions got renamed:
- nrf_gpiote_int_is_enabled to nrf_gpiote_int_enable_check
- nrf_gpiote_event_is_set to nrf_gpiote_event_check
- nrf_rng_event_get to nrf_rng_event_check
- nrf_rng_int_get to nrf_rng_int_enable_check
- nrf_rtc_event_pending to nrf_rtc_event_check
- nrf_rtc_int_is_enabled to nrf_rtc_int_enable_check
- nrf_timer_cc_read to nrf_timer_cc_get
- nrf_timer_cc_write to nrf_timer_cc_set

Default configuration values were removed from nrfx_config files,
so the drivers pwm_nrfx and spi_nrfx_spis no longer can use those.

Function nrfx_pwm_init() now takes one more parameter - context pointer
that is passed to the event handler, not used in the pwm_nrfx driver.

HALs for UART and UARTE now allow configuration of the parity type
and the number of stop bits, for SoCs that provide the corresponding
registers.

2b61031c8f kconfig: Remove symbol types from Kconfig.defconfig files
Same deal as in commit 7fdb525754 ("kconfig: Use 'default' instead of
'def_bool' in Kconfig.defconfig files"), but I hacked Kconfiglib to also
find cases where the type is given separately as e.g.

    config FOO
            int
            default 3

Motivation (from a note in
https://docs.zephyrproject.org/latest/guides/kconfig/index.html):

    For a symbol defined in multiple locations (e.g., in a
    Kconfig.defconfig file in Zephyr), it is best to only give the
    symbol type for the "base" definition of the symbol, and to use
    'default' (instead of 'def_<type>' value) for the remaining
    definitions. That way, if the base definition of the symbol is
    removed, the symbol ends up without a type, which generates a
    warning that points to the other definitions. That makes the extra
    definitions easier to discover and remove.

It's also nice if 'def_bool' and the like turn into a semi-reliable flag
that the symbol is only defined in Kconfig.defconfig files. That might
be a sign that things could be cleaned up.

Will do a separate pass later to remove some symbols only defined in
Kconfig.defconfig files.

677f1e6db9 kconfig: Turn pointless/confusing 'menuconfig's into 'config's
Defining a symbol with 'menuconfig' just tells the menuconfig to display
any dependent symbols that immediately follow it in a separate menu.
'menuconfig' has no effect on symbol values.

Making a symbol that doesn't have any dependent symbols after it a
'menuconfig' should be avoided, because then you end up with an empty
menu, which is shown as e.g.

    [*] Enable foo ---

This is how it would be shown if there were children but they all
happened to be invisible as well.

With a regular 'config', it turns into

    [*] Enable foo

Change all pointless 'menuconfig's to 'config's.

See the section on 'menuconfig' on the Kconfig - Tips and Best Practices
page as well.

7c7db00a77 drivers: adc: add driver support for ADC1 of stm32
This commit adds driver support for ADC1 on all 8 supported series of
stm32 with resolution and conversion time selection and calibration.

Currently DMA is not supported for all series, and without it, zephyr
won't be able to catch up ADC's end of conversion interrupt, so this
version of the driver supports one channel conversion only. Users want
multi-channel conversion should use multiple sequences in their app
code.

This driver uses LL lib rather than HAL because the current HAL lib for
ADC will call HAL_DMA_* functions rather than using zephyr's common DMA
interface, so that way the driver will break the consistency of the
code.

This driver has been tested on multiple nucleo boards including
NUCLEO_F091RC/F103RB/F207ZG/F302R8/F401RE/F746ZG/L073RZ/L476RG and all
passed the test cases in tests/drivers/adc/adc_api. If the external ADC
line is floating, it may fail the tests since ADC may get 0V and the
test cases think 0 is failing. Connect it to any voltage source between
0-3.3V will help passing the test cases.

Since commit 0906a51dac, the driver
fails the test: tests/drivers/adc/adc_api. Some of the workflow
turns out to be incorrect (e.g. not doing dummy conversion after
getting out of deep power down, and not clearing interrupt status
bits). So take some time to overhaul the driver. Also rename
the driver to adc_intel_quark_se_c1000_ss because the inner

After initialization with the default values, the clock source
of the ADC is asynchronous clock (ADACK) and clock divide ratio
is 8. The minimum conversion clock frequency is 1MHz.
Add clock divider selection and set default divide ratio to 1.
That sets the conversion clock frequency to approximately 5MHz.

Default configuration for the voltage reference is set to
external pins V_REFH and V_REFL. Depending on the MCU configuration
V_REFL may be connected to ground and V_REFH to VREF_OUT.
Since Voltage Reference block is not supported, the ADC does not work

20202902f2 dts_fixups: Use DT_ prefix in all defined labels not related to Kconfig
These changes were obtained by running a script  created by
Ulf Magnusson <Ulf.Magnusson@nordicsemi.no> for the following
specification:

1. Read the contents of all dts_fixup.h files in Zephyr
2. Check the left-hand side of the #define macros (i.e. the X in
   #define X Y)
3. Check if that name is also the name of a Kconfig option
   3.a If it is, then do nothing
   3.b If it is not, then replace CONFIG_ with DT_ or add DT_ if it
       has neither of these two prefixes
4. Replace the use of the changed #define in the code itself
   (.c, .h, .ld)

Additionally, some tweaks had to be added to this script to catch some
of the macros used in the code in a parameterized form, e.g.:
- CONFIG_GPIO_STM32_GPIO##__SUFFIX##_BASE_ADDRESS
- CONFIG_UART_##idx##_TX_PIN
- I2C_SBCON_##_num##_BASE_ADDR
and to prevent adding DT_ prefix to the following symbols:
- FLASH_START
- FLASH_SIZE
- SRAM_START
- SRAM_SIZE
- _ROM_ADDR
- _ROM_SIZE
- _RAM_ADDR
- _RAM_SIZE
which are surprisingly also defined in some dts_fixup.h files.

Finally, some manual corrections had to be done as well:
- name##_IRQ -> DT_##name##_IRQ in uart_stm32.c

Does not yet support some of the channel configuration options such as
gain and reference voltage because the hardware only allows these

f1891e9473 drivers: adc: Introduce reworked API
This commit replaces the API for ADC drivers with a reworked one.
As requested in the issue #3980, the adc_enable/adc_disable functions
are removed. Additionaly, some new features are introduced, like:
- asynchronous calls
- configuration of channels
- multi-channel sampling

Common parts of code that are supposed to appear in each implementation
of the driver (like locking, synchronization, triggering of consecutive
samplings) are provided in the "adc_context.h" file to keep consistency
with the SPI driver. Syscalls are no longer present in the API because
the functions starting read requests cannot use them, since they can be
provided with a callback that is executed in the ISR context, and there
is no point in supporting syscalls only for the channels configuration.

"adc_api" test is updated and extended with additional test cases,
with intention to show how the API is supposed to be used.
"adc_simple" test is removed as it does not seem to add much value.

8345e5ebf0 syscalls: remove policy from handler checks
The various macros to do checks in system call handlers all
implictly would generate a kernel oops if a check failed.
This is undesirable for a few reasons:

* System call handlers that acquire resources in the handler
  have no good recourse for cleanup if a check fails.
* In some cases we may want to propagate a return value back
  to the caller instead of just killing the calling thread,
  even though the base API doesn't do these checks.

These macros now all return a value, if nonzero is returned
the check failed. K_OOPS() now wraps these calls to generate
a kernel oops.

At the moment, the policy for all APIs has not changed. They
still all oops upon a failed check/

The macros now use the Z_ notation for private APIs.

b0db28b512 drivers: Cmake: Add __ZEPHYR_SUPERVISOR__ macro for driver files.
Normally a syscall would check the current privilege level and then
decide to go to _impl_<syscall> directly or go through a
_handler_<syscall>.
__ZEPHYR_SUPERVISOR__ is a compiler optimization flag which will
make all the system calls from the driver files directly link
to the _impl_<syscall>. Thereby reducing the overhead of checking the
privileges.

In the previous implementation all the source files would be compiled
by zephyr_source() rule. This means that zephyr_* is a catchall CMake
library for source files that can be built purely with the include
paths, defines, and other compiler flags that all zephyr source
files uses. This states that adding one extra compiler flag for only
one complete directory would fail.
This limitation can be overcome by using zephyr_libray* APIs. This
creates a library for the required directories and it also supports
directory level properties.
Hence we use zephyr_library* to create a new library with
macro _ZEPHYR_SUPERVISOR_ for the optimization.

12f8f76165 Introduce cmake-based rewrite of KBuild
Introducing CMake is an important step in a larger effort to make
Zephyr easy to use for application developers working on different
platforms with different development environment needs.

Simplified, this change retains Kconfig as-is, and replaces all
Makefiles with CMakeLists.txt. The DSL-like Make language that KBuild
offers is replaced by a set of CMake extentions. These extentions have
either provided simple one-to-one translations of KBuild features or
introduced new concepts that replace KBuild concepts.

This is a breaking change for existing test infrastructure and build
scripts that are maintained out-of-tree. But for FW itself, no porting
should be necessary.

For users that just want to continue their work with minimal
disruption the following should suffice:

Install CMake 3.8.2+

Port any out-of-tree Makefiles to CMake.

Learn the absolute minimum about the new command line interface:

$ cd samples/hello_world
$ mkdir build && cd build
$ cmake -DBOARD=nrf52_pca10040 ..

$ cd build
$ make

c93a4789cb drivers: adc: add system call handlers
Straightforward conversion for adc_enable/disable.

adc_read() uses a sequence table, which points to an array
of struct adc_seq_entry, each element pointing
to memory buffers. Need to validate all of these as being readable

789081673f Introduce new sized integer typedefs
This is a start to move away from the C99 {u}int{8,16,32,64}_t types to
Zephyr defined u{8,16,32,64}_t and s{8,16,32,64}_t.  This allows Zephyr
to define the sized types in a consistent manor across all the
architectures we support and not conflict with what various compilers
and libc might do with regards to the C99 types.

We introduce <zephyr/types.h> as part of this and have it include
<stdint.h> for now until we transition all the code away from the C99
types.

We go with u{8,16,32,64}_t and s{8,16,32,64}_t as there are some
existing variables defined u8 & u16 as well as to be consistent with
Zephyr naming conventions.

unnecessary typecasts aren't needed for that either (if the data

ff8138595e adc: adjustments to dummy read
Per Curie documentation, the first sample from the Quark SE ADC
hardware after reset needs to be dropped.
This commits changes the location and the trigger event to do
a dummy read that drops the first sample.
Originally the driver did the dummy read on the API call enable()
and it was triggered if the ADC had awakened from suspend mode.
Because the SoC is not in suspend mode on power on and the API
enable() call has no information on the channels to be read the
dummy read could be missed.
Now the dummy read is done on the API call to read()
and triggered if it is the first time read() is called
since power on.

41771e5b1c adc: Repetitive buffer management
This commit changes the behavior of the driver when it reports
buffer results back through the callback.

Originally, the driver reported a callback after each sequence
table round signaled by an interrupt. If in repetitive mode,
each reported result was put in the next buffer element,
which was considered circular, and reported back with callback.

Now the behavior changes. If in repetitive mode, each sequence table
round reported by an interruption puts the data  in next element of
the reception buffer. The callback reports back once the buffer is
fulled and stops the sampling process.

d9cfbd5a61 interrupts: new static IRQ API
The interrupt API has been redesigned:

- irq_connect() for dynamic interrupts renamed to irq_connect_dynamic().
  It will be used in situations where the new static irq_connect()
  won't work, i.e. the value of arguments can't be computed at build time
- a new API for static interrupts replaces irq_connect(). it is used
  exactly the same way as its dynamic counterpart. The old static irq
  macros will be removed
- Separate stub assembly files are no longer needed as the stubs are now
  generated inline with irq_connect()

ReST documentation updated for the changed API. Some detail about the
IDT in ROM added, and an oblique reference to the internal-only
_irq_handler_set() API removed; we don't talk about internal APIs in
the official documentation.
