Kernel 3.19 and SPI support

[shug]

Hello all,
I used to work on my A20 board with v3.4 kernel and the fex/bin files to enable spi support (/dev/spidevX.X).
I just switch to a new image with a v3.19 kernel and it seems that there isn't any fex/bin files anymore but a "dtb" folder with .dtb compiled files.
Do you know ho to manage with these files ?
Thank you
xavier

These are so called Device trees, see http://elinux.org/Device_Trees or maybe Device Tree for Dummies from the Linux Foundation at the http://events.linuxfoundation.org/sites/events/files/slides/petazzoni-device-tree-dummies.pdf. They are the way how to manage devices on ARM platform on almosts everything other than Allwinner SoCs. They work similar to the FEX files, so you must edit the source (DTS) first, them compile it into the binary format (DTB) to use.
