标题: x3399点亮需要初始化的mipi屏
我现在用android-7.1,kernel-4.4的sdk，点亮一块需要初始化的mipi屏。
用下面的方式初始化，但在mipi数据线上量不到数据:
107 &mipi_dsi {
108    status = "okay";
109    panel {
110       compatible ="simple-panel-dsi";
111       reg = <0>;
112       backlight = <&backlight>;
113       enable-gpios = <&gpio1 13 GPIO_ACTIVE_HIGH>;
114       dsi,flags = <(MIPI_DSI_MODE_VIDEO | MIPI_DSI_MODE_VIDEO_BURST | MIPI_DSI_MODE_VIDEO_SYNC_PULSE)>;
115       dsi,format = <MIPI_DSI_FMT_RGB888>;
116       dsi,lanes = <4>;
117       status = "okay";
118       panel-init-sequence = [
119          15 00 02 B0 5A
120          15 00 02 B1 00
121          15 00 02 89 01
122          15 00 02 91 17
123          15 00 02 B1 03
124          15 00 02 2C 28
125          15 00 02 00 F1
126             ];
127
128       display-timings {
129          native-mode = <&timing0>;
130          timing0: timing0 {
131                clock-frequency = <158000000>;
132                hactive = <1920>;
133                vactive = <1200>;
134                hback-porch = <54>;
135                hfront-porch = <64>;
136                vback-porch = <10>;
137                vfront-porch = <8>;
138                hsync-len = <50>;
139                vsync-len = <6>;
140                hsync-active = <0>;
141                vsync-active = <0>;
142                de-active = <0>;
143                pixelclk-active = <0>;
144          };
145       };
146    };
147 };
请问下要怎么把初始化数据写入屏中呢？
