-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):

-Example bindings:

-tcu: tcu {
- compatible = "nvidia,tegra194-tcu";
- mboxes = <&hsp_top0 TEGRA_HSP_MBOX_TYPE_SM 0>,
- <&hsp_aon TEGRA_HSP_MBOX_TYPE_SM 1>;
