Hi Simon,
This patch serie move tpm_tis_i2c driver to tpm_tis_infineon.
It also convert the latest tpm driver tpm_atmel_twi to DM_TPM.
In this version i am only adding mention to Tom Rini review
Best Regards
Christophe

As there is no TCG specification or recommendation for i2c TPM 1.2,
move tpm_tis_i2c driver to tpm_i2c_infineon. Other tpm vendors like Atmel
or STMicroelectronics may have a different transport protocol for i2c.

As every TPM drivers support UCLASS_TPM, we can only rely on DM_TPM
functions.
This simplify a bit the code.

Hi Simon,
This error is coming from the fact that no driver model is available for
powerpc and the config file mention in the error log
(controlcenterd_36BIT_SDCARD, controlcenterd_36BIT_SDCARD_DEVELOP,
controlcenterd_TRAILBLAZER, controlcenterd_TRAILBLAZER_DEVELOP).
Do you think converting atmel driver to dm_tpm without dm_i2c dependency is
acceptable as a first step ? It would help to clean the TPM driver model.
Do you think it make sense to convert powerpc i2c driver to i2c_dm ?
Best Regards
Christophe
