ea81b4b812 drivers: display_nrf_led_matrix: Correct calculation of pixel period
This is a follow-up to commit 4dfab40cac.

The calculation of the pixel period is done incorrectly and results
in higher than configured refresh frequency if pixels are refreshed
in groups. Fix that and lower the base frequency for the timer and
PWM so that wider range of refresh frequency can be used also with
the pixel grouping.

4dfab40cac drivers: display_nrf_led_matrix: Add option to light LEDs in groups
Add a new DT property named "pixel-group-size" that allows users to
configure the driver to refresh the matrix by illuminating multiple
LEDs in particular rows simultaneously. This way the maximum possible
brightness of the LEDs can be increased (as they can be lit longer)
and the timer interrupt handler is executed less frequently, what
results in decreased CPU load, but more GPIOTE/PPI channels needs to
be allocated if the PWM peripheral cannot be used. Thus, it is left
to users to select the configuration that suits them best.

Update definitions of both the bbc_microbit boards with this new
property, using the maximum available group size (to achieve maximum
possible brightness). For v2, no new resources are used (only all
channels in the already used PWM peripheral are now utilized).
For v1, two more GPIOTE and PPI channels are allocated.

Some display drivers may actually be initialized after LittlevGL
as those drivers and LittlevGL's lvgl_init() all have SYS_INIT()
at APPLICATION and init priority the same as application init
priority. Depending on how the final binary is linked, these
drivers may initialize after lvgl_init() resulting in it not
able to find a display driver. This changes the value of
CONFIG_DISPLAY_INIT_PRIORITY so that the display drivers that
make use of this kconfig are initialized a bit earlier to
ensure that they are actually initialized before lvgl_init().

8b8e8f99ba display: introduce CONFIG_DISPLAY_INIT_PRIORITY
This introduces a new kconfig CONFIG_DISPLAY_INIT_PRIORITY
to specify the initialization priority for display devices.
Most of the display devices are using APPLICATION and
CONFIG_APPLICATION_INIT_PRIORITY which is not entirely
appropriate for devices. Due to linking order, the display
device may be initialized after application code at same
init level and priority. This results in the display device
not ready to be used for application code. So this kconfig
option allows the display devices to be initialized earlier
if needed.

For the drivers using CONFIG_APPLICATION_INIT_PRIORITY,
they have been changed to use CONFIG_DISPLAY_INIT_PRIORITY
instead.

Note that the default value for CONFIG_DISPLAY_INIT_PRIORITY
is the same as CONFIG_APPLICATION_INIT_PRIORITY at 90 to
avoid any functional changes.

7ccc1a41bc pm: use actions for device PM control
Instead of passing target states, use actions for device PM control.
Actions represent better the meaning of the callback argument.
Furthermore, they are more future proof as they can be suitable for
other PM actions that have no direct mapping to a state. If we compare
with Linux, we could have a multi-stage suspend/resume. Such scenario
would not have a good mapping when using target states.

Use the core k_heap API pervasively within our tree instead of the
z_mem_pool wrapper that provided compatibility with the older mempool
implementation.

Almost all of this is straightforward swapping of one alloc/free call
for another.  In a few cases where code was holding onto an old-style
"mem_block" a local compatibility struct with a single field has been
swapped in to keep the invasiveness of the changes down.

Note that not all the relevant changes in this patch have in-tree test

b4a3880a75 drivers: remove unnecessary use of DEVICE_AND_API_INIT

cases that look like:

  #ifdef CONFIG_DEVICE_POWER_MANAGEMENT
    DEVICE_DEFINE()
  #else
    DEVICE_AND_API_INIT()
  #endif

There is no need to special case this as the pm_control_fn argument to
DEVICE_DEFINE will just be ignored in the
!CONFIG_DEVICE_POWER_MANAGEMENT case.  So we can cleanup the code a
little and remove the #else cases for the drivers that do this.

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.

7832738ae9 kernel/timeout: Make timeout arguments an opaque type
Add a k_timeout_t type, and use it everywhere that kernel API
functions were accepting a millisecond timeout argument.  Instead of
forcing milliseconds everywhere (which are often not integrally
representable as system ticks), do the conversion to ticks at the
point where the timeout is created.  This avoids an extra unit
conversion in some application code, and allows us to express the
timeout in units other than milliseconds to achieve greater precision.

The existing K_MSEC() et. al. macros now return initializers for a
k_timeout_t.

The K_NO_WAIT and K_FOREVER constants have now become k_timeout_t
values, which means they cannot be operated on as integers.
Applications which have their own APIs that need to inspect these
vs. user-provided timeouts can now use a K_TIMEOUT_EQ() predicate to
test for equality.

Timer drivers, which receive an integer tick count in ther
z_clock_set_timeout() functions, now use the integer-valued
K_TICKS_FOREVER constant instead of K_FOREVER.

For the initial release, to preserve source compatibility, a
CONFIG_LEGACY_TIMEOUT_API kconfig is provided.  When true, the
k_timeout_t will remain a compatible 32 bit value that will work with
any legacy Zephyr application.

Some subsystems present timeout (or timeout-like) values to their own
users as APIs that would re-use the kernel's own constants and
conventions.  These will require some minor design work to adapt to
the new scheme (in most cases just using k_timeout_t directly in their
own API), and they have not been changed in this patch, instead
selecting CONFIG_LEGACY_TIMEOUT_API via kconfig.  These subsystems
include: CAN Bus, the Microbit display driver, I2S, LoRa modem
drivers, the UART Async API, Video hardware drivers, the console
subsystem, and the network buffer abstraction.

k_sleep() now takes a k_timeout_t argument, with a k_msleep() variant
provided that works identically to the original API.

Most of the changes here are just type/configuration management and
documentation, but there are logic changes in mempool, where a loop
that used a timeout numerically has been reworked using a new
z_timeout_end_calc() predicate.  Also in queue.c, a (when POLL was
enabled) a similar loop was needlessly used to try to retry the
k_poll() call after a spurious failure.  But k_poll() does not fail
spuriously, so the loop was removed.

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.

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'.

975de21858 kconfig: Global whitespace/consistency cleanup
Clean up space errors and use a consistent style throughout the Kconfig
files. This makes reading the Kconfig files more distraction-free, helps
with grepping, and encourages the same style getting copied around
everywhere (meaning another pass hopefully won't be needed).

Go for the most common style:

 - Indent properties with a single tab, including for choices.

   Properties on choices work exactly the same syntactically as
   properties on symbols, so not sure how the no-indentation thing
   happened.

 - Indent help texts with a tab followed by two spaces

 - Put a space between 'config' and the symbol name, not a tab. This
   also helps when grepping for definitions.

 - Do '# A comment' instead of '#A comment'

I tweaked Kconfiglib a bit to find most of the stuff.

Some help texts were reflowed to 79 columns with 'gq' in Vim as well,
though not all, because I was afraid I'd accidentally mess up
formatting.

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.

d0afacc6b4 display: ssd1673: replace k_busy_wait by k_sleep
The SSD1673 driver currently use k_busy_wait to wait for the
controller to finish the execution of a commmand. However a display
update command can take from a few hundreds of ms (default LUT) to
almost a second (initial LUT). k_busy_wait is just a spinning loop,
which prevents all the threads with lower priority to not be executed
during that time. That could be the case for example of the shell or
the log thread.

As the timing is not critical, it's better to use k_sleep instead,
allowing the CPU to process other threads. In the long term it might
even be better to use an interrupt there, but might not be that easy if
we want to support to various SoCs that can be connected to such a
display.

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

1becbfcb8b drivers: display: ssd1673: Fixup dts support
There were several issues in the dts binding for the ssd1673 display:
* binding file mixed description & generation up together
* Use of BASE_LABEL
* orientation-flipped should have been of type boolean

Update the binding file to reflect these changes, and made associated
changes to dts_fixup.h and driver as needed.

060b8c1512 drivers: ssd1306: fixup dts support
A few issues with the dts support for the SSD1306 display driver:
1. binding file mixed description & generation up together
   - rename most uses of generation to description and add proper
     generation field into yaml
2. Drop use of BASE_LABEL, this shouldn't be used by most bindings
3. dts defines that are being assumed in driver aren't correct.  We
   should be using a dts_fixup.h in the sample to map the generated
   defines to those used in the driver.  We remove the incorrect
   defines that the driver assumes right now.
4. Fixup 'segment-remap' and 'com-invdir' properties that are booleans
   in the binding file and associated code changes.

8cf8db3a73 Kconfig: Use a short, consistent style for prompts
Consistently use

    config FOO
            bool/int/hex/string "Prompt text"

instead of

    config FOO
            bool/int/hex/string
            prompt "Prompt text"

(...and a bunch of other variations that e.g. swapped the order of the
type and the 'prompt', or put other properties between them).

The shorthand is fully equivalent to using 'prompt'. It saves lines and
avoids tricking people into thinking there is some semantic difference.

Most of the grunt work was done by a modified version of
https://unix.stackexchange.com/questions/26284/

38185db8fd drivers: display: Kconfig: Remove redundant 'default n' properties
Bool symbols implicitly default to 'n'.

A 'default n' can make sense e.g. in a Kconfig.defconfig file, if you
want to override a 'default y' on the base definition of the symbol. It
isn't used like that on any of these symbols though, and is
inconsistent.

This will make the auto-generated Kconfig documentation have "No
defaults. Implicitly defaults to n." as well, which is clearer than
'default n if ...'

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

65a9d2a94a kernel: make K_.*_INITIALIZER private to kernel
Upcoming memory protection features will be placing some additional
constraints on kernel objects:

- They need to reside in memory owned by the kernel and not the
application
- Certain kernel object validation schemes will require some run-time
initialization of all kernel objects before they can be used.

Per Ben these initializer macros were never intended to be public. It is
not forbidden to use them, but doing so requires care: the memory being
initialized must reside in kernel space, and extra runtime
initialization steps may need to be peformed before they are fully
usable as kernel objects. In particular, kernel subsystems or drivers
whose objects are already in kernel memory may still need to use these
macros if they define kernel objects as members of a larger data
structure.

It is intended that application developers instead use the
K_<object>_DEFINE macros, which will automatically put the object in the
right memory and add them to a section which can be iterated over at
boot to complete initiailization.

There was no K_WORK_DEFINE() macro for creating struct k_work objects,
this is now added.

k_poll_event and k_poll_signal are intended to be instatiated from
application memory and have not been changed.

7574bebbfe drivers/display: mb_display: Use 4 ms refresh timer
The code was so far requesting 5 ms refresh timer, however with a
default TICKS_PER_SECOND=100 this was always rounded up to 10 ms,
causing some flickering. The closest TICKS_PER_SECOND that will give
flicker-less display but also give optimal ms-to-ticks calculations is
250, so change the timer to match that. After this change any code
using the display is recommended to set 250 as ticks per second.
