BeagleConnect is both a technology concept and a line of board designs that implement the technology. Born from Greybus, a mechanism for dynamically extending a Linux system with embedded peripherals, BeagleConnect adds two key elements: a 6LoWPAN transport and mikroBUS manifests. The 6LoWPAN transport provides for arbitrary connections, including the IEEE802.15.4g long-range wireless transport supported between BeaglePlay and BeagleConnect Freedom (the first BeagleConnect board design). The mikroBUS manifests provide for rapid prototyping and low-node-count production with sensor boards following the mikroBUS freely-licensable embedded bus standard such that existing Linux drivers can be loaded upon Greybus discovery of the nodes.
This patch set provides the Linux-side hooks required for the 6LoWPAN transport for BeagleConnect on BeaglePlay. Also adds required devicetree additions.
Tested over `next-20230825`.
