From d886c0009bd087ebf76e345ad0ce155240be5898 Mon Sep 17 00:00:00 2001 From: "Nancy.Lin" Date: Tue, 21 Mar 2023 20:18:54 +0800 Subject: drm/mediatek: Add ETHDR support for MT8195 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.
