From 26e0ca64917cd310727f524ec4f07ce84278fd48 Mon Sep 17 00:00:00 2001 From: Heiko Stuebner Date: Sun, 24 Dec 2023 19:39:02 +0100 Subject: [PATCH v3 3/3] arm64: dts: rockchip: add overlay for tiger-haikou video-demo adapter This adds support for the video-demo-adapter DEVKIT ADDON CAM-TS-A01 (https://embedded.cherry.de/product/development-kit/) for the Haikou devkit with Tiger RK3588 SoM. The Video Demo adapter is an adapter connected to the fake PCIe slot labeled "Video Connector" on the Haikou devkit. It's main feature is a Leadtek DSI-display with touchscreen and a camera (that is not supported yet). To drive these components a number of additional regulators are grouped on the adapter as well as a PCA9670 gpio-expander to provide the needed additional gpio-lines.
