[PATCH 0/2] tpm: fix locality and power saving handling

[Tomas Winkler]

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
