* 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>; |
|
}; |
|
};
