[PATCH 6.12 060/369] staging: greybus: gbphy: fix up const issue with the match callback

by Greg Kroah-Hartman

6.12-stable review patch. If anyone has any objections, please let me know. ------------------ From: Greg Kroah-Hartman <gregkh(a)linuxfoundation.org> [ Upstream commit ce32eff1cf3ae8ac2596171dd0af1657634c83eb ] gbphy_dev_match_id() should be taking a const pointer, as the pointer passed to it from the container_of() call was const to start with (it was accidentally cast away with the call.) Fix this all up by correctly marking the pointer types.

[RFC 0/6] Introducing CPC support in Greybus

by Damien Riégel

Hi, This patchset brings support for Silicon Labs' CPC protocol as transport layer for Greybus. As an example, a SPI driver is added as physical layer and everything is bundled as a big kernel module. In the future, as we plan to support other physical layers like SDIO, CPC core will be its own module, and each physical layer CPC driver will be its own module as well. CPC implements some of the features of Unipro that Greybus relies upon, like reliable transmission. CPC takes care of detecting transmission errors and retransmit frames if necessary. There's also a flow-control feature, preventing sending messages to full cports. In addition to the host device over SPI part, there's also a class driver for a vendor protocol that enables Bluetooth on supported devices. This is mostly there to open the discussion on how a new protocol should be added to Greybus.

Your call. Also, gives you also the chance to practice to send a new version ;).
