+Required properties:
+- compatible: Should be "st,st33htpm-spi" or "infineon,slb9670" or "tcg,tpm_tis-spi"
+- spi-max-frequency: Maximum SPI frequency (depends on TPMs).
+
+Optional TPM_TIS SPI Properties:
+- interrupt-parent: phandle for the interrupt gpio controller
+- interrupts: GPIO interrupt to which the chip is connected
+
+Optional SoC Specific Properties:
+- pinctrl-names: Contains only one value - "default".
+- pintctrl-0: Specifies the pin control groups used for this controller.
