Linux 6.7 USB/Thunderbolt Adds DP Alt Mode 2.1 Support, Intel LJCA

The USB/Thunderbolt subsystem updates were merged a few days ago for Linux 6.7. As Greg Kroah-Hartman put it in the pull request, "nothing really major in here, just lots of constant development for new hardware."

Among the new support with Linux 6.7 is adding the necessary bits to the USB Type-C driver for handling DisplayPort Alternate Mode 2.1 support. This DP Alt Mode 2.1 support over Type-C has been plumbed into the Type-C driver as well as the necessary bits being added to the cros_ec_typec driver used by Google Chromebooks as well as the Intel PMC MUX driver for being able to configure DisplayPort Alternate Mode 2.1 setups.

The other notable addition on the USB side this kernel cycle is adding Intel La Jolla Cove Adapter (LJCA) drivers. The Intel La Jolla Cove Adapter drivers are used as part of the Intel Vision Sensing Controller functionality.

Other new bits include IPQ5018, RK3588, Realtek DHC RTD SoC, and SDX75 hardware support in the DWC3 driver. The DWC3 Xilinx driver code has also added reset controller support.

More details on all of the USB/Thunderbolt feature changes for Linux 6.7 via the USB pull. The Linux 6.7 merge window ends today with the release of Linux 6.7-rc1.
