imx6solox lvds linux 4.1.15

 When uboot starts,I can see NXP logo,but when kernel starts ,lcd is black ,when all the rootfs boot finished,  i cat  /proc/cmdline ,i found the lvds lcd Parameters are not passed。

the log message is below

backlight1 supply power not found, using dummy regulator
backlight2 supply power not found, using dummy regulator
2224000.lcdif supply lcd not found, using dummy regulator
mxsfb 2224000.lcdif: failed to find mxc display driver ldb

cmdline is console=ttymxc0,115200 root=/dev/mmcblk3p2 rootwait rw.

I think it is caused by the parameter not being passed。But I don’t know where to configure to solve this problem。

I found that a lot of documents about lvds transplantation are linux 3. version。Is there a detailed step-by-step introduction to LVDS LCD transplantation of Linux 4.1.15 version

about kernel ,i only config the imx6sx-sdb.dtsi,Are there other places to configure

Looking forward to your reply

But what you gave is not for the linux4.1.15 kernel. Do you have any information about the 4.1.15 kernel?
