+* TZLOG (Trust Zone Log)
+
+The tz_log driver is a platform device driver that exposes a debugfs
+interface for accessing and displaying diagnostic information
+related to secure code (Trustzone/QSEE).
+
+Required properties:
+- compatible : Should be "qcom,tz-log"
+- reg : Offset and size of the register set for the device
+
+Example:
+
+ qcom,tz-log@fe805720 {
+ compatible = "qcom,tz-log";
+ reg = <0xfe805720 0x1000>;
+ };
