	ETHDR is a part of ovl_adaptor. ETHDR is designed for HDR video and graphics conversion in the external display path. It handles multiple HDR input types and performs tone mapping, color space/color format conversion, and then combine different layers, output the required HDR or SDR signal to the subsequent display path.
