[PATCH v2 0/2] tpm: add driver for cr50 on SPI

[Andrey Pronin]

This patchset adds support for H1 Secure Microcontroller running
Cr50 firmware. It implements several functions, including TPM-like
functionality, and communicates over SPI using the FIFO protocol
described in the PTP Spec, section 6.
H1 is a proprietary chip that the Chrome OS team is investigating
for inclusion in future Chromebooks.

Depends on the following patchset:
 - tpm_tis_core: add optional max xfer size check

v2: Removed driver-specific sysfs attributes.
    Compatible id changed to cr50 from cr50_spi.
    Updated descriptions of the supported device/interface.
