Kernel-4.18.0-80.el8_tpm-i2c

• Device Tree Bindings for I2C based Trusted Platform Module(TPM)

Required properties:

• compatible : ‘manufacturer,model’, eg. nuvoton,npct650
• label : human readable string describing the device, eg. “tpm”
• linux,sml-base : 64-bit base address of the reserved memory allocated for

               the firmware event log
  

• linux,sml-size : size of the memory allocated for the firmware event log

Optional properties:

• powered-while-suspended: present when the TPM is left powered on between

                       suspend and resume (makes the suspend/resume
                       callbacks do nothing).
  

Example (for OpenPower Systems with Nuvoton TPM 2.0 on I2C)

tpm@57 {
reg = <0x57>;
label = “tpm”;
compatible = “nuvoton,npct650”, “nuvoton,npct601”;
linux,sml-base = <0x7f 0xfd450000>;
linux,sml-size = <0x10000>;
};
