bananapi m3 MIPI DSI (S070WV20HG-) how to make it work?

Hello guys!

i had download armbian for bananapi m3(a83t) from arambian for bpi-m3. And braking my mind with friending sinovoip LCD+touchscreen module.

I tried all the known options for me to connect the LCD display S070WV20HG-DC16 with the touchscreen on the ft5x_ts driver,  and failed because apparently not smart enough for this, the my brains are exploding.

In the kernel, I did not find the drivers on the display (S070WV20_MIPI_RGB)
and the driver on the screen in the kernel is not compiled.

Is anyone can correct in the device tree file the parameters for the LCD section for the display as I understood the data can be taken from the fex file:

pull in the kernel driver for the display for compilation from here:S070WV20_MIPI_RGB.c

And make correct Device tree binary file(dtb),Uboot and drivers for kernel.

 I will award beer for the implemented solution
