Compiling dts files

Hello everybody 

I expose my problem ...

I create my own a20 card ( based on olimex a20 lime) ( 90% similar )

I have no problem with the hardware ....all work except ....leds  ( you know in /sys/class/leds ....)

But i need 3 leds ... so i write this in dts file ( sun7i-a20-olinuxino-lime.dts)

It work fine with 4.4xx version of kernel and armbian 5

But i need some 4.6.1 functionnality's 

So i download the armbian 5.14 ( and i build kernel 4.6.1)

All hardware is ok and work except leds

After a ./ compile  ( completed ) , i changed the the dts file  with my leds parameters ...and nothing ....I have only the "green" led (in /sys/class/leds/ )

So i suppose that dts files were compiled the first time and will be never compiled again Or .... if you have a solution it will be cool !
