Problem building staging drivers (fbtft)

[Cesar Gutierrez]

I downloaded the source code from here https://github.com/OnionIoT/source

make menuconfig
and selected the required options

I also configured the kernel to load the staging drivers

make kernel_menuconfig

Device drivers -> Graphics support -> Frame buffer Devices -> Support for frame buffer devices
Device drivers -> Staging drivers -> Support for small TFT LCD display modules

<M> FB driver for the ST7735R LCD Controller
<M> Generic FB driver for TFT LCD displays
<M> Module to for adding FBTFT devices

make -j5 V=s

I flashed the Omega with the bin generated.

sysupgrade -n lede-ramips-mt7688-omega2p-squashfs-sysupgrade.bin

But when is time to use the module, it doesn't work, I've tried all of this:

insmod fb_defio
insmod fb
insmod fbtft

modeprobe fbtft

fbtft_device

and nothing works, I don't think the module is correctly configured
Am I missing something?
