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

by 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`.

[PATCH][next] staging: greybus: Add __counted_by for struct apr_rx_buf and use struct_size()

by Gustavo A. R. Silva

Prepare for the coming implementation by GCC and Clang of the __counted_by attribute. Flexible array members annotated with __counted_by can have their accesses bounds-checked at run-time via CONFIG_UBSAN_BOUNDS (for array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family functions). While there, use struct_size() helper, instead of the open-coded version, to calculate the size for the allocation of the whole flexible structure, including of course, the flexible-array member. This code was found with the help of Coccinelle, and audited and fixed manually. Signed-off-by: Gustavo A. R.
