Hi 其东

in general i.IMX7D can not support both parallel LCD and DSI as

both use one eLCDIF module. Porting will be performing specific for panel

configuration commands, setting timings using sect.6.4 MIPI DSI attached Linux Manual

and example of TRULY-WVGA-TFT3P5581E display, which is supported by default

(reference can be found in arch/arm/boot/dts/imx7d-sdb-mipi-dsi.dts)

linux-imx.git - i.MX Linux Kernel 

static struct fb_videomode truly_lcd_modedb[] = {
{
"TRUULY-WVGA", 50, 480, 854, 41042,
40, 60,
3, 3,
8, 4,
FB_SYNC_OE_LOW_ACT,
FB_VMODE_NONINTERLACED,
0,
},
};

Best regards
igor

Hello, I don't know how to build the device tree. I tried to port the content from imx7d-sdb-mipi-dsi.dts, but without success, can you give a transplanted document and sample?
