Trusted Computing Group MMIO Trusted Platform Module |
|
|
|
The TCG defines multi vendor standard for accessing a TPM chip, this |
|
is the standard protocol defined to access the TPM via MMIO. Typically |
|
this interface will be implemented over Intel's LPC bus. |
|
|
|
Refer to the 'TCG PC Client Specific TPM Interface Specification (TIS)' TCG |
|
publication for the specification. |
|
|
|
Required properties: |
|
|
|
- compatible: should contain a string below for the chip, followed by |
|
"tcg,tpm-tis-mmio". Valid chip strings are: |
|
* "atmel,at97sc3204" |
|
- reg: The location of the MMIO registers, should be at least 0x5000 bytes |
|
- interrupts: An optional interrupt indicating command completion. |
|
|
|
Example: |
|
|
|
tpm_tis@90000 { |
|
compatible = "atmel,at97sc3204", "tcg,tpm-tis-mmio"; |
|
reg = <0x90000 0x5000>; |
|
interrupt-parent = <&EIC0>; |
|
interrupts = <1 2>; |
|
};
