Description
***********
.. code-block:: none
Worldsemi WS2812 LED strip, GPIO binding
Driver bindings for bit-banging a WS2812 or compatible LED strip.
The GPIO driver uses inline assembly, and isn't available for all
boards.
Properties
**********
.. tabs::
.. group-tab:: Node specific properties
Properties not inherited from the base binding file.
.. list-table::
:widths: 1 1 4

* - Name
- Type
- Details
* - ``in-gpios``
- ``phandle-array``
- .. code-block:: none
GPIO phandle and specifier for the pin connected to the daisy
chain's input pin. Exactly one pin should be given.
This property is **required**.
* - ``chain-length``
- ``int``
- .. code-block:: none
The number of devices in the daisy-chain.
This property is **required**.
* - ``has-white-channel``
- ``boolean``
- .. code-block:: none
If true, the device has a white channel. This is not supported
by the led_strip.h API, so the white data on the wire will be
zero if set.
.. group-tab:: Deprecated node specific properties
Deprecated properties not inherited from the base binding file.
(None)
.. group-tab:: Base properties
Properties inherited from the base binding file, which defines
common properties that may be set on many nodes. Not all of these
may apply to the "worldsemi,ws2812-gpio" compatible.
