Devices that support locality has failed to transmit due to reserved order of locality request and cmdReady/goIdle handshake. The cmdReady/goIdle should be performed on the requested locality.
The first patch corrects the locality and power-save order, adds required polling for completion of goIdle and locality relinquish.
The second patch removes cmdRead/goIdle handshake from runtime_pm as it's rather a part of TPM2 protocol then true device power management, and on device it's no longer optional.
Tomas Winkler (2): tpm: cmd_ready command can be issued only after granting locality tpm: separate cmd_ready/go_idle from runtime_pm
