The WS2812 LED driver IC has a one-wire interface which encodes bit
values as pulse widths.
The ICs themselves are basically shift registers. Roughly speaking, a
"short" pulse shifts in a zero bit, a "long" pulse shifts in a one
bit, and an inter-pulse gap exceeding a reset time threshold causes a
pixel to latch the shifted-in color values. Each chip has an output
pin for daisy chaining. Refer to the chip datsheets and comments in
Kconfig.ws2812 for more details.
To meet timing without hogging the core, this driver generates pulses
using SPI. To work, this requires the MOSI line to stay low between
SPI frames, and for inter-frame delays to be less than the reset pulse
time.
There are other ways do it (PWM + DMA on some SoCs, GPIO bit-banging
if no other tasks need the core), but this is a reasonably
general-purpose implementation.

LPD880x (e.g. LPD8803, LPD8806) devices are LED driver ICs which can
be controlled via a reduced SPI interface (clock and data only), and
support daisy chaining.
Add an led_strip driver for these devices.

This API covers drivers for strips, or strings, of individually
addressable LEDs. Both RGB and grayscale LED strip drivers can be
implemented within these APIs.
The API only provides for updating the entire strip, since not all
strips support updating individual LEDs without affecting the others.
Subsequent patches will add individual driver support.

When the header file is located in the same directory as the source
file it is better to use a relative quote-include, e.g.
than a system include like
Avoiding the use of system includes in these cases is beneficial
because;
* The source code will be easier to build because there will be fewer
system include paths.
* It is easier for a user to determine where a quote-include header
file is located than where a system include is located.
* You are less likely to encounter aliasing issues if the list of
system include paths is minimized.

No need to send FCS bytes as the monitor_15_4 is configured to not
expect them. If we change the monitor_15_4 to use them, then we would
need to put correct values into these two FCS bytes.
So cleanest solution is not to send FCS bytes at all.

Loopback is a networking interface which doesn't actually transfer
any data via link layer externally, and instead just mirrors back
(i.e. any packet send to the loopback interface will be received from
it). This interface very useful for testing.

There are several issues with the dev_config union used as a
convenience when calling the i2c_configure api. One, the union is well
name spaced protected and doesn't convey use with just i2c. Second
there are assumptions of how the bits might get packed by the union
which can't be guaranteed. Since the API takes a u32_t lets change in
tree uses to using the macros to setup a u32_t and make the union as
deprecated.
