| Required properties: | |
| - compatible: should be one of the following | |
| "st,st33htpm-spi" | |
| "infineon,slb9670" | |
| "tcg,tpm_tis-spi" | |
| - spi-max-frequency: Maximum SPI frequency (depends on TPMs). | |
| Optional SoC Specific Properties: | |
| - pinctrl-names: Contains only one value - "default". | |
| - pintctrl-0: Specifies the pin control groups used for this controller. | |
| Example (for ARM-based BeagleBoard xM with TPM_TIS on SPI4): | |
| &mcspi4 { | |
| tpm_tis@0 { | |
| compatible = "tcg,tpm_tis-spi"; | |
| spi-max-frequency = <10000000>; | |
| }; | |
| }; |
