TOKITA Hiroshi 0702f0eb45 drivers: led_strip: ws2812_gpio: Rename in-gpios property to gpios
ws2812-gpio's `in-gpios` property is not used as an input pin.
Renaming it to `gpios` to reflect the actual situation.

Gerard Marull-Paretas 79e6b0e0f6 includes: prefer <zephyr/kernel.h> over <zephyr/zephyr.h>
As of today <zephyr/zephyr.h> is 100% equivalent to <zephyr/kernel.h>.
This patch proposes to then include <zephyr/kernel.h> instead of
<zephyr/zephyr.h> since it is more clear that you are including the
Kernel APIs and (probably) nothing else. <zephyr/zephyr.h> sounds like a
catch-all header that may be confusing. Most applications need to
include a bunch of other things to compile, e.g. driver headers or
subsystem headers like BT, logging, etc.

The idea of a catch-all header in Zephyr is probably not feasible
anyway. Reason is that Zephyr is not a library, like it could be for
example `libpython`. Zephyr provides many utilities nowadays: a kernel,
drivers, subsystems, etc and things will likely grow. A catch-all header
would be massive, difficult to keep up-to-date. It is also likely that
an application will only build a small subset. Note that subsystem-level
headers may use a catch-all approach to make things easier, though.

NOTE: This patch is **NOT** removing the header, just removing its usage
in-tree. I'd advocate for its deprecation (add a #warning on it), but I
understand many people will have concerns.

MISRA C:2012 Rule 14.4 (The controlling expression of an if statement
and the controlling expression of an iteration-statement shall have
essentially Boolean type.)

Use `do { ... } while (false)' instead of `do { ... } while (0)'.
Use comparisons with zero instead of implicitly testing integers.

Simon Guinot 4ada0bbd6e led_strip: ws2812: allow to configure channel mapping
Some devices compatibles with the WS2812 IC have a different channel to
color mappings (e.g. RGB, BGR, RGBW, etc).

This patch introduces the "color-mapping" required property for the
WS2812 DT binding and adds support to the ws2812_gpio and ws2812_spi
drivers. This new property allows to configure the color to channel
mapping of a WS2812 compatible LED strip controller from its DT node.

Since this property also allows to know if a white channel is available,
then this patch removes the "has-white-channel" property.

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

Martí Bolívar 1d2a551c65 drivers: led_strip: modernize and fix up ws2812 drivers/sample
Convert the GPIO based driver to the new GPIO API. (Only the
gpio_configure() call is affected).

Move configuration to DT where appropriate for both SPI and GPIO
drivers, only leaving the SPI vs. GPIO decision in Kconfig (in
addition to the basic enable for the driver.) Move some files around
to clean up as a result of this change.

led_ws2812 sample changes:

- make the pattern easier to look at by emitting less light

- use led_strip alias from DT to get strip device, allocate
  appropriate struct led_rgb buffer, etc.

- move the pins around and remove 96b_carbon support (I have no board
  to test with)

GPIO driver specific changes:

- str is required to write OUTSET/OUTCLR, not strb. The registers
  are word-sized.

- the str[b] registers must all be in r0-r7, so "l" is the correct GCC
  inline assembly constraint for both "base" and "pin"

SPI driver specific changes:

- match the GPIO driver in not supporting the update_channels API
  method, which never made sense for this type of strip

- return -ENOMEM when the user tries to send more pixel data
  than we have buffer space for instead of -EINVAL
