Merge tag 'tag-chrome-platform-for-v6.5' of git://git.kernel.org/pub/…

…scm/linux/kernel/git/chrome-platform/linux

Pull chrome platform updates from Tzung-Bi Shih:
 "Improvements:

   - Support Pin Assignment D in getting mux state

   - Emit an uevent when EC panics so that userland programs get chance
     to capture EC coredumps (LPC interface only)

   - Send EC_CMD_HOST_SLEEP_EVENT to EC at the very beginning/end of
     system suspend/resume so that EC can watch the duration more
     accurately (LPC interface only)

  Misc:

   - Switch back from I2C .probe_new() to .probe()

   - Use %*ph for printing hexdump of small buffers"
