Mika writes: thunderbolt: Changes for v5.11 merge window This includes following Thunderbolt/USB4 changes for v5.11 merge window: * DMA traffic test driver * USB4 router NVM upgrade improvements * USB4 router operations proxy implementation available in the recent Intel Connection Manager firmwares * Support for Intel Maple Ridge discrete Thunderbolt 4 controller * A couple of cleanups and minor improvements. * tag 'thunderbolt-for-v5.11-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/westeri/thunderbolt: (22 commits) thunderbolt: Add support for Intel Maple Ridge thunderbolt: Add USB4 router operation proxy for firmware connection manager thunderbolt: Move constants for USB4 router operations to tb_regs.h thunderbolt: Add connection manager specific hooks for USB4 router operations thunderbolt: Pass TX and RX data directly to usb4_switch_op() thunderbolt: Pass metadata directly to usb4_switch_op() thunderbolt: Perform USB4 router NVM upgrade in two phases thunderbolt: Return -ENOTCONN when ERR_CONN is received thunderbolt: Keep the parent runtime resumed for a while on device disconnect thunderbolt: Log adapter numbers in decimal in path activation/deactivation thunderbolt: Log which connection manager implementation is used thunderbolt: Move max_boot_acl field to correct place in struct icm MAINTAINERS: Add Isaac as maintainer of Thunderbolt DMA traffic test driver thunderbolt: Add DMA traffic test driver thunderbolt: Add support for end-to-end flow control thunderbolt: Make it possible to allocate one directional DMA tunnel thunderbolt: Create debugfs directory automatically for services thunderbolt: Add functions for enabling and disabling lane bonding on XDomain thunderbolt: Add link_speed and link_width to XDomain thunderbolt: Create XDomain devices for loops back to the host ...
