The Tegra Combined UART (TCU) is a mailbox-based mechanism that allows multiplexing multiple "virtual UARTs" into a single hardware serial port. The TCU is the primary serial port on Tegra194 devices. Add a TCU driver utilizing the mailbox framework, as the used mailboxes are part of Tegra HSP blocks that are already controlled by the Tegra HSP mailbox driver.
