+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";
+ };
+ };
