   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).
