[PATCH] Revert "staging: greybus: Fix capitalization and punctuation inconsistencies"

by Johan Hovold

This reverts commit 30db8460f984a7f5299b6e07ea8a57cd09fc9557. The offending commit tried to make the error messages of a few Greybus drivers in staging more consistent by capitalising messages, but the rest of the Greybus code do not follow this style so the change ended up introducing an inconsistency instead.

[PATCH v3 0/3] Add Firmware Upload support for beagleplay cc1352

by Ayush Singh

Adds support for beagleplay cc1352 co-processor firmware upgrade using kernel Firmware Upload API. Uses ROM based bootloader present in cc13x2x7 and cc26x2x7 platforms for flashing over UART. Communication with the bootloader can be moved out of gb-beagleplay driver if required, but I am keeping it here since there are no immediate plans to use the on-board cc1352p7 for anything other than greybus (BeagleConnect Technology). Additionally, there do not seem to any other devices using cc1352p7 or its cousins as a co-processor. Bootloader backdoor and reset GPIOs are used to enable cc1352p7 bootloader backdoor for flashing. Flashing is skipped in case we are trying to flash the same image as the one that is currently present. This is determined by CRC32 calculation of the supplied firmware and flash data. We also do a CRC32 check after flashing to ensure that the firmware was flashed properly.

[PATCH 0/3] Add Firmware Upload support for beagleplay cc1352

by Ayush Singh

Adds support for beagleplay cc1352 co-processor firmware upgrade using kernel Firmware Upload API. Uses ROM based bootloader present in cc13x2x7 and cc26x2x7 platforms for flashing over UART. Communication with the bootloader can be moved out of gb-beagleplay driver if required, but I am keeping it here since there are no immediate plans to use the on-board cc1352p7 for anything other than greybus (BeagleConnect Technology). Additionally, there do not seem to any other devices using cc1352p7 or it's cousins as a co-processor. Boot and Reset GPIOs are used to enable cc1352p7 bootloader backdoor for flashing. Flashing is skipped in case we are trying to flash the same image as the one that is currently present. This is determined by CRC32 calculation of the supplied firmware and Flash data. We also do a CRC32 check after flashing to ensure that the firmware was flashed properly.

[PATCH] staging: greybus: Enclose multi-statement macro in do-while loop

by Juan José Arboleda

The macro `gb_loopback_stats_attrs` in the Greybus loopback driver contains multiple statements, which should be enclosed in a do-while loop to ensure proper execution and adhere to coding standards. This patch modifies the `gb_loopback_stats_attrs` macro to enclose its statements in a do-while loop, addressing the style error flagged by checkpatch.pl.
