The Silergy SY7758 is an I2C-controlled multi-channel LED backlight driver used to drive the edge-lit LED strings of LCD panels. It is present on the Ayaneo Pocket DS handheld, where it drives the panel backlight, and is required before the panel can be lit.
This series adds the device tree binding for the new "silergy,sy7758" compatible and the matching driver. The driver registers a backlight class device with a 12-bit linear brightness range and programs the chip's mode and current configuration registers on the first non-zero brightness update. The Ayaneo Pocket DS device tree, posted as a separate series, depends on the binding introduced here to describe its panel backlight.
