    1 * Device Tree Bindings for I2C based Trusted Platform Module(TPM)
    2 
    3 Required properties:
    4 
    5 - compatible     : 'manufacturer,model', eg. nuvoton,npct650
    6 - label          : human readable string describing the device, eg. "tpm"
    7 - linux,sml-base : 64-bit base address of the reserved memory allocated for
    8                    the firmware event log
    9 - linux,sml-size : size of the memory allocated for the firmware event log
   10 
   11 Optional properties:
   12 
   13 - powered-while-suspended: present when the TPM is left powered on between
   14                            suspend and resume (makes the suspend/resume
   15                            callbacks do nothing).
   16 
   17 Example (for OpenPower Systems with Nuvoton TPM 2.0 on I2C)
   18 ----------------------------------------------------------
   19 
   20 tpm@57 {
   21         reg = <0x57>;
   22         label = "tpm";
   23         compatible = "nuvoton,npct650", "nuvoton,npct601";
   24         linux,sml-base = <0x7f 0xfd450000>;
   25         linux,sml-size = <0x10000>;
   26 };
