-Turris Mox rWTM firmware driver
-
-Required properties:
- - compatible          : Should be "cznic,turris-mox-rwtm"
- - mboxes              : Must contain a reference to associated mailbox
-
-This device tree node should be used on Turris Mox, or potentially another A3700
-compatible device running the Mox's rWTM firmware in the secure processor (for
-example it is possible to flash this firmware into EspressoBin).
-
-Example:
-
-       firmware {
-               turris-mox-rwtm {
-                       compatible = "cznic,turris-mox-rwtm";
-                       mboxes = <&rwtm 0>;
-                       status = "okay";
-               };
