Enable driver for WS2812 (and compatibles) LED strip using SPI.

The SPI driver is portable, but requires significantly more
|

memory (1 byte of overhead per bit of pixel data).

Enable driver for WS2812 (and compatibles) LED strip using I2S.
|
|
Uses the I2S peripheral, memory usage is 4 bytes per color,
|
|
times the number of pixels. A few more for the start and end
|
|
delay. The reset delay has a coarse resolution of ~20us.

Enable driver for WS2812 (and compatibles) LED strip directly controlling with GPIO.
|
|
The GPIO driver does bit-banging with inline assembly,
|
|
and is not available on all SoCs.
|
|
|
|
Note that this driver is not compatible with the Everlight B1414
|
|
controller.
