From 32ddc0d9f7186471c2f1ae8dc7279639dcaadb06 Mon Sep 17 00:00:00 2001 From: Hung-Te Lin Date: Wed, 7 Aug 2019 10:58:36 +0800 Subject: soc/mediatek/mt8183: Add DSI driver The MT8183 display serial interface (DSI) is based on MIPI Alliance Specification, supporting high-speed serial data transfer between host processor and peripheral devices such as display modules. DSI supports both video mode and command mode data transfer defined in MIPI spec, and it also provides bidirectional transmission with low-power mode to receive messages from the peripheral.
