From: YİĞİTCAN KAVAKLI <redacted> Add devicetree binding documentation for the Kinetic Technologies KTD3136 3-channel LED backlight driver using the official "kinetic" vendor prefix. The device is controlled over I2C and supports an optional hardware enable GPIO line (enable-gpios), supply regulators, and standard backlight brightness range properties.
