| * 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>;
| };
| };
