We need to ensure that all DMAs and interrupts are cleared during

Otherwise, HW could be performing a DMA into random addresses in the
middle of second kernel start.

This is an attempt to convert tpm_tis over to using the locality
callbacks added by Jarkko's tpm_crb patch. Requires the patch
currently on tpmdd/locality which has moved the need_locality
assignment inside the mutex in tpm_transmit.
This is pretty much the same as Jarkko's earlier patch (I think)
This patch converts tpm_tis to use of the new tpm class ops
request_locality, and relinquish_locality.
With the move to using the callbacks, release_locality is changed so
that we now release the locality even if there is no request pending.
This required some changes to the tpm_tis_core_init cod

Hi Thomas,
Thank you very much for a very insightful feedback. I will address your

Hey Rafael,
have you seen this already (partial splat photo attached)? Happens
during resume from s2d. Judging by the timestamps, this looks like the
resume kernel before we switch to the original, boot one but I could be
mistaken.

The ethtool api {get|set}_settings is deprecated.
We move this driver to new api {get|set}_link_ksettings.
As I don't have the hardware, I'd be very pleased if
someone may test this patch.

Hmm. Sad. The label approach looked like it would match the semantics
of cmpxchg perfectly, but it's not as optimal as it superficially
would have seemed.
