[U-Boot] Device Tree for U-Boot

Hi,

I'm new to Device Tree. I have u-boot running on a imx6solo custom board. I would like to use device tree instead of way I'm have it currently configured. Where should I start to get an understanding of device tree? I know that I would need to create a dts file for my board and I have gone over some examples. But, where can I get some documentation on the various properties listed under each node to make some sense as to their meaning.

Best regards,
