+* Device Tree Bindings for I2C PTP based Trusted Platform Module(TPM)
+
+Required properties:
+
+- compatible : Should be "tcg,tpm_i2c_ptp"
+- reg : Address on the bus
+- tpm-pirq : Input gpio pin, used for host interrupts
+
+Example (for Raspberry Pie 3 Board with Nuvoton's NPCT75X (2.0)
+-------------------------------------------------------------------
+
+tpm_i2c_ptp: tpm_i2c_ptp@2e {

+ compatible = "tcg,tpm_i2c_ptp";
+ reg = <0x2e>;
+ tpm-pirq = <&gpio 24 GPIO_ACTIVE_HIGH>;
+};
