MIPI 屏
- 配置PAD为MIPI模式：
修改 vi infinity2m-ssc011a-s01a-padmux-display.dtsi配置为mipi模式# vi infinity2m-ssc011a-s01a-padmux-display.dtsi

- 修改ChannelSwap的值：
(MI_PANEL_ChannelSwapType_e)2, (MI_PANEL_ChannelSwapType_e)4, (MI_PANEL_ChannelSwapType_e)3, (MI_PANEL_ChannelSwapType_e)1, (MI_PANEL_ChannelSwapType_e)0,
默认的PAD引脚和MIPI对应功能如下：
如果实际电路连接不一致，则需要修改ChannelSwap的值：
修改的规则如下:
首先对PAD和lane进行分组
并清楚eCh0-4所代表的意义
这里举一个实例，D0-D3分别对接屏的D0-D3，CK对接屏的CK,因此得出下表:
- 根据屏厂提供的初始化代码，修改初始化数组：
- 修改stMipiDsiConfig的值：
MI_PANEL_MipiDsiConfig_t stMipiDsiConfig =
{
//HsTrail HsPrpr HsZero ClkHsPrpr ClkHsExit ClkTrail ClkZero ClkHsPost DaHsExit ContDet
