This includes following Thunderbolt/USB4 changes for the v6.1 merge window: - Support for Intel Meteor Lake integrated Thunderbolt/USB4 controller - Support for ASMedia USB4 controller NVM firmware upgrade - Receiver lane margining support - Few fixes and cleanups. All these have been in linux-next with no reported issues. -----BEGIN PGP SIGNATURE----- iQJUBAABCgA+FiEEVTdhRGBbNzLrSUBaAP2fSd+ZWKAFAmM0G3ogHG1pa2Eud2Vz dGVyYmVyZ0BsaW51eC5pbnRlbC5jb20ACgkQAP2fSd+ZWKAhEg/8CuUZvDwLog7O SbpKAPqGOvDC3EM0VhtJyjJAUVWImVaRuSHAWEHn/XJAICaRTxMJJM7xoJnr+X7O 4VMFzPhF6oF+28VMzy8OLm15kiiNtpXimOKaXNXzoDzJ6aqjgr9KpHSpzhOx3MuF HUzhoMWk2RHwnrkxlpewU9wJg8ZtG6syI5QV534KsqIwxOcO+8pr7nKz8V8HrUt9 EwFIgU4op/eKCsgeLmotw/8CXI33ezIheMeUdSit3Gqa3Ey9u/JtzVaN7siEOhxy c3nBO8MgYhKaX0RCVKFGRm/YktFlrECStfDNhgtUbBS2lfoePcaeZGKwuCRpmhkj WicPxph8m5slKborqGVaoZtgtxqftOt1tWmvnJntqSLcOycPM4bX8gDfWZmoi6JX f+Vritdy9DDTCE00/Hc2gCpQG0rfX+DzpYvLz4Z8tIa5oU9X5CfCNs8qb20VSQAg xgmyRe+6/UzJAMKQ7uPy8wSKt/rpKOxsIQC+bhhdiN9g000YS7A56juiC0Z8IfrH rZae7pvtoD/r7lrJlRcFKtNPup+QrZZ/kdLzWpZbAmKYZ7DkI44KA4iHVBpt24rg 8e23s2/U6ezhNMcR0dLWwIrE+KoiB15BkX9/J1CJxhJLW9lw+fxlSfeZDI0rfjE2 HqcC/Fxx1dMNJykbXAyrO9HYmT551Vs= =67d1 -----END PGP SIGNATURE----- Merge tag 'thunderbolt-for-v6.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/westeri/thunderbolt into usb-next Mika writes: "thunderbolt: Changes for v6.1 merge window This includes following Thunderbolt/USB4 changes for the v6.1 merge window: - Support for Intel Meteor Lake integrated Thunderbolt/USB4 controller - Support for ASMedia USB4 controller NVM firmware upgrade - Receiver lane margining support - Few fixes and cleanups.

USB4 and Thunderbolt driver. USB4 is the public specification
|
|
based on the Thunderbolt 3 protocol. This driver is required if
|
|
you want to hotplug Thunderbolt and USB4 compliant devices on
|
|
Apple hardware or on PCs with Intel Falcon Ridge or newer.
|
|
|
|
To compile this driver a module, choose M here. The module will be
|
|
called thunderbolt.

help
|
|
Enables writing to device configuration registers through
|
|
debugfs interface.
|
|
|
|
Only enable this if you know what you are doing! Never enable
|
|
this for production systems or distro kernels.

help
|
|
Enables hardware and software based receiver lane margining support
|
|
under each USB4 port. Used for electrical quality and robustness
|
|
validation during manufacturing. Should not be enabled by distro
|
|
kernels.

This allows sending and receiving DMA traffic through loopback
|
|
connection. Loopback connection can be done by either special
|
|
dongle that has TX/RX lines crossed, or by simply connecting a
|
|
cable back to the host. Only enable this if you know what you
|
|
are doing. Normal users and distro kernels should say N here.
|
|
|
|
To compile this driver a module, choose M here. The module will be
|
|
called thunderbolt_dma_test.
