From 23f965a4c611e5c2d2576b5f8d2aa2ea6fffb24c Mon Sep 17 00:00:00 2001 From: Yannick Fertré Date: Mon, 7 Oct 2019 15:29:05 +0200 Subject: dm: Add a dsi host uclass MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Display Serial Interface (DSI) host can usefully be modelled as their own uclass. DSI defines a serial bus and a communication protocol between the host and the device (panel, bridge).
