Re: [PATCH v2 5/6] drivers: tpm: atmel_twi: implement get_desc operation

Without get_desc, the tpm command will not provide a description of the device in 'tpm device' or 'tpm info'.

Due to the characteristics of the Atmel TPM it isn't possible to determine certain attributes (e.g open/close status) without using the TPM stack (compare Infineon and ST TPM drivers), so just print out the chip model and udevice name as the identifier.
