| H A D | sb_regs.h | d0f1e0c2 Tue Feb 22 11:31:47 CST 2022 Mika Westerberg <mika.westerberg@linux.intel.com> thunderbolt: Add support for receiver lane margining
USB4 spec defines standard set of registers to be used for receiver lane
margining. This is useful for I/O interface quality and electrical
robustness validation during manufacturing. Expose receiver lane
margining through new debugfs directory "margining" that is added under
each connected USB4 port. Users can then run the margining by writing to
the exposed attributes under that directory.
