| * H1 Secure Microcontroller with Cr50 Firmware on SPI Bus. | |
| H1 Secure Microcontroller running Cr50 firmware provides several | |
| functions, including TPM-like functionality. It communicates over | |
| SPI using the FIFO protocol described in the PTP Spec, section 6. | |
| Required properties: | |
| - compatible: Should be "google,cr50". | |
| - spi-max-frequency: Maximum SPI frequency. | |
| Example: | |
| &spi0 { | |
| tpm@0 { | |
| compatible = "google,cr50"; | |
| reg = <0>; | |
| spi-max-frequency = <800000>; | |
| }; | |
| }; |
