| 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 { |
| |
| status = "okay"; |
| |
| tpm_tis@0 { |
| |
| compatible = "tcg,tpm_tis-spi"; |
| |
| spi-max-frequency = <10000000>; |
| }; |
| }; |
