this sounds nice. Eric and i, aren't not Raspberry Pi maintainer
anymore. Nicolas Saenz Julienne is the current one. But it's preferred
to send such request to linux-rpi-kernel at lists.infradead.org
(subscription required).

I assume you are talking about $id and $schema URI. There aren't URL so
you won't find anything there. Before this YAML files there were simple
text describing the usage of the device tree [1]. They were easier to
understand for beginners :-(

For devicetree there aren't much documentation: [2] [3]

For driver development, i'm have any recommendation for a recent book. I
suggest to share your plans to the linux-rpi-kernel, so we can discuss
the next steps.
