* 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>;
|
|
};
|
|
};
