[PATCH RFC 01/10] dt-bindings: backlight: add Kinetic KTD3136

["YİĞİTCAN KAVAKLI via B4 Relay" <devnull+kavakliyigitcan.gmail.com@kernel.org>]

From: YİĞİTCAN KAVAKLI <kavakliyigitcan@gmail.com>

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.
