This chip provides an eDP to LVDS bridge which is useful for SoCs that don't support LVDS displays (or it would waste scarce pins). There is no setup required by this chip, other than to adjust power-down and reset pins, and those are managed by the uclass. Signed-off-by: Simon Glass <sjg@chromium.org>
