This patchset adds a TCG TPM2.0 PTP FIFO compliant interface for
Cr50 chip on SPI.
Depends on the following patches by Andrey Pronin <apro...@chromium.org>
that add new members to phy_ops in tpm_tis_core:
- tpm: support driver-specific sysfs attrs in tpm_tis_core
- tpm_tis_core: add op
This patchset adds a TCG TPM2.0 PTP FIFO compliant interface for
Cr50 chip on SPI.
Depends on the following patches by Andrey Pronin
that add new members to phy_ops in tpm_tis_core:
- tpm: support driver-specific sysfs attrs in tpm_tis_core
- tpm_tis_core: add optional max xfer size check
Break sysfs attributes into common and TPM 1.2/2.0-specific, and
create sysfs groups for TPM2.0.

- TPM2.0

This patchset introduces an optional maximum transfer size that can
be specified by a tpm driver. Setting the max_xfer_size helps to catch
the cases when burstcnt is incorrectly reported by the device (e.g. >64
for spi - happened in practice) and gracefully handle such situations.
