[PATCH v8 0/3] greybus: Add BeaglePlay Greybus Driver

[Ayush Singh]

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`.
