+* Device Tree Bindings for I2C PTP based Trusted Platform Module(TPM)
+
+The TCG defines hardware protocol, registers and interface (based
+on the TPM Interface Specification) for accessing TPM devices
+implemented with an I2C interface.
+
+Refer to the 'I2C Interface Definition' section in 'TCG PC Client
+PlatformTPMProfile(PTP) Specification' publication for specification.
+
+Required properties:
+
+- compatible     : Should be "tcg,tpm_tis-i2c"
+- 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_tis-i2c: tpm_tis-i2c@2e {
+
+       compatible = "tcg,tpm_tis-i2c";
+       reg = <0x2e>;
+       tpm-pirq = <&gpio 24 GPIO_ACTIVE_HIGH>;
+};
