+title: LED driver for LP50XX RGB LED from Texas Instruments.
+
+maintainers:
+ - Dan Murphy <dmurphy@ti.com>
+
+description: |
+ The LP50XX is multi-channel, I2C RGB LED Drivers that can group RGB LEDs into
+ a LED group or control them individually.
+
+ The difference in these RGB LED drivers is the number of supported RGB
+ modules.

Introduce the bindings for the Texas Instruments LP5036, LP5030, LP5024, LP5018, LP5012 and LP5009 RGB LED device driver. The LP5036/30/24/18/12/9 can control RGB LEDs individually or as part of a control bank group. These devices have the ability to adjust the mixing control for the RGB LEDs to obtain different colors independent of the overall brightness of the LED grouping.
