Alexandre Bourdiol 5559430654 driver: counter: counter_ll_stm32_rtc.c: Add 1 tick to alarm
Add +1 tick to alarm in order to compensate the partially started tick.
Alarm will expire between requested ticks and ticks+1.
In case only 1 tick is requested, it will avoid that +1 Tick event
occurs before alarm setting is finished.

Martí Bolívar 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.

Peter Bigot 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.

Martí Bolívar 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

Peter A. Bigot e444274e95 drivers: counter: add Maxim DS3231 support
The DS3231 is an I2C real-time clock with internal temperature
compensated oscillator, maintaining civil time to 1 s precision with
nominal 2 ppm accuracy from 0-40 Cel.

The basic functionality is exposed as a counter that is always running
at 1 Hz.  Much more functionality is exposed as driver-specific API,
including the ability to translate between the time scale of the DS3231
and the time scale of the Zephyr uptime clock.  This allows correlation
of events in the system clock to UTC, TAI, or whatever time scale is
used to maintain the DS3231.

Martí Bolívar 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.

Ulf Magnusson eddd98f811 kconfig: Replace some single-symbol 'if's with 'depends on'
I think people might be reading differences into 'if' and 'depends on'
that aren't there, like maybe 'if' being needed to "hide" a symbol,
while 'depends on' just adds a dependency.

There are no differences between 'if' and 'depends on'. 'if' is just a
shorthand for 'depends on'. They work the same when it comes to creating
implicit menus too.

The way symbols get "hidden" is through their dependencies not being
satisfied ('if'/'depends on' get copied up as a dependency on the
prompt).

Since 'if' and 'depends on' are the same, an 'if' with just a single
symbol in it can be replaced with a 'depends on'. IMO, it's best to
avoid 'if' there as a style choice too, because it confuses people into
thinking there's deep Kconfig magic going on that requires 'if'.

Going for 'depends on' can also remove some nested 'if's, which
generates nicer symbol information and docs, because nested 'if's really
are so simple/dumb that they just add the dependencies from both 'if's
to all symbols within.

Replace a bunch of single-symbol 'if's with 'depends on' to despam the
Kconfig files a bit and make it clearer how things work. Also do some
other minor related dependency refactoring.

The replacement isn't complete. Will fix up the rest later. Splitting it
a bit to make it more manageable.

(Everything above is true for choices, menus, and comments as well.)

Detected by tweaking the Kconfiglib parsing code. It's impossible to
detect after parsing, because 'if' turns into 'depends on'.

The previous counter driver API function for reading the current value
of the counter (counter_read()) did not support indicating whether the

while they are actually handled by single peripheral with single

Implementation changes some time ago and subsys parameter was

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_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.
