     13description:
     14  The TCU is a system for sharing a hardware UART instance among multiple
     15  systems within the Tegra SoC. It is implemented through a mailbox-
     16  based protocol where each "virtual UART" has a pair of mailboxes, one
     17  for transmitting and one for receiving, that is used to communicate
     18  with the hardware implementing the TCU.
