| Enable LED strip driver for daisy chains of LPD880x |
| (LPD8803, LPD8806, or compatible) devices. |
| |
| Each LPD880x LED driver chip has some output channels |
| (3 channels for LPD8803, 6 for LPD8806), whose PWM |
| duty cycle can be set at 7 bit resolution via a |
| reduced SPI interface (MOSI and CLK lines only). |
| Each chip also includes data and clock out pins for |
| daisy chaining LED strips. |
