+NVIDIA Tegra Combined UART (TCU)
+
+The TCU is a system for sharing a hardware UART instance among multiple
+systems within 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"
+- mbox-names:
+    "rx" - Mailbox for receiving data from hardware UART
+    "tx" - Mailbox for transmitting data to hardware UART
+- mboxes: Mailboxes corresponding to the mbox-names.
+
+This node is a mailbox consumer. See the following files for details of
+the mailbox subsystem, and the specifiers implemented by the relevant
+provider(s):
+
+- .../mailbox/mailbox.txt

-	   to the external serial line, whereas the second clock
-	   must correspond to the PCLK clocking the internal logic
-	   of the block. Just listing one clock (the first one) is
-	   deprecated.
-- clock-names:
-	   When present, the first clock listed must be named
-	   "uartclk" and the second clock listed must be named
-	   "apb_pclk"
-- dmas:	
-	   When present, may have one or two dma channels.

-- clocks : phandle to the input clock
-
-The supplying peripheral clock can also be handled, needing a second property

-Optional properties:

-  configuration parameter. Define this if your UART does not implement the busy
-  functionality.
-- resets : phandle to the parent reset controller.
-- reg-shift : quantity to shift the register offsets by.  If this property is
-  not present then the register offsets are not shifted.
-- reg-io-width : the size (in bytes) of the IO accesses that should be
-  performed on the device.  If this property is not present then single byte
-  accesses are used.
-- dcd-override : Override the DCD modem status signal. This signal will always
-  be reported as active instead of being obtained from the modem status
-  register. Define this if your serial port does not use this pin.
-- dsr-override : Override the DTS modem status signal. This signal will always
