- compatible		: Should be "tcg,tpm_tis-spi"
- reg			: SPI Chip select

Optional properties:
- reset-gpios		: Reset GPIO (if not connected to the SoC reset line)
- gpio-reset		: Reset GPIO (deprecated, use reset-gpios instead)
- spi-max-frequency	: See spi-bus.txt

		compatible = "tcg,tpm_tis-spi";
		reg = <1>;
		spi-max-frequency = <10000000>;
	};
