以RK3399为例,其提供了两路MIPI DSI通道,分别是dsi@ff960000和dsi1: dsi@ff968000,代表MIPI DSI host。 2050 dsi: dsi@ff960000 { 2051 compatible = "rockchip,rk3399-mipi-dsi"; 2052 reg = <0x0 0xff960000 0x0 0x8000>; ... 2083 dsi1: dsi@ff968000 { 2084 compatible = "rockchip,rk3399-...

该数据结构由DRM MIPI DSI提供,用以描述DSI Host所能提供的功能函数,包括DSI Host和显示屏之间创建联结关系需要使用的attach、通过DSI Host配置显示屏的transfer。 3. MIPI DSI软件架构 基于DRM的图显系统中,MIPI DSI子系统主要由DSI CORE与PANEL CORE组成,二者内建链接关系后注册到DRM CORE系统。 MIPI DSI软件架构...
具体而言,用的是LP的LPDT模式,只需要用到data_lane0, LPDT流程如下(参考dphy文档): 进入Escape mode: LP11-10-00-01-00 LPDT指令:8'h87, Space-One-Hot编码,低位先发。 发送DCS配置命令,如generic short write命令。有时为了便于观察波形,可以每8bit插入一段LP00 发送LP10-11: 退出Escape mode 注:时钟通...
