Subject: [PATCH] dt-bindings: leds: backlight: ktz8866: Add reg property and update example
Date:   Sat, 29 Apr 2023 00:02:46 +0800
Message-Id: <20230428160246.16982-1-lujianhua000@gmail.com>

The kinetic,ktz8866 is a I2C driver, so add the missing reg property.
And update example to make it clear.
