+NVIDIA Tegra Combined UART (TCU)
+
+The TCU is a system for sharing a hardware UART instance among multiple
+systems withing the Tegra SoC. It is implemented through a mailbox-
+based protocol where each "virtual UART" has a pair of mailboxes, one
+for transmitting and one for receiving, that is used to communicate
+with the hardware implementing the TCU.
+
+Required properties:
+- name : Should be tcu
+- compatible
+    Array of strings
+    One of:
+    - "nvidia,tegra194-tcu"

Nit. We should say what device the above compatibility is applicable for ...

    - "nvidia,tegra194-tcu": for Tegra194

Cheers
Jon
