The Kandou KB9002 is an 8-lane PCIe 5.0 retimer with an integrated
microcontroller that exposes an SMBus 3.0 target (with mandatory PEC)
on its sideband interface. Its firmware aggregates per-lane die
temperatures and publishes the maximum through a register window.

This series adds a hwmon driver for it. The driver reports the
aggregated maximum die temperature as temp1_input, and exposes the
running firmware version and boot status under debugfs.

The series is organised as:

  1/4  add the "kandou" vendor prefix
  2/4  device tree binding for the retimer
  3/4  the driver, Kconfig/Makefile and MAINTAINERS entry
  4/4  hwmon documentation
