Texas Instruments TLC5971 (and compatible) LED controller
Driver bindings for daisy chains of a TLC5971 devices using a single device
tree node. Length of daisy chains in pixels is defined by the chain-length
property. Note: chain-length must be a multiple of 4. A single TLC5971 device
supports 4 RGB LEDs.
The color order of the TLC5971 is BGR. Applications can provide custom mappings
using the color-mapping property.
Example device tree node w. 24 pixels (6 TLC5971 devices):
&spi1 {
led_controller: led_controller@0 {
status = "okay";
compatible = "ti,tlc59711", "ti,tlc5971";
spi-max-frequency = <DT_FREQ_M(1)>;
reg = <0x0>;
chain-length = <24>;
color-mapping = <LED_COLOR_ID_BLUE>,
<LED_COLOR_ID_GREEN>,
<LED_COLOR_ID_RED>;
};
};
compatible: "ti,tlc5971"
