[PATCH 0/2] tpm: add optional max xfer size check

From: Andrey Pronin
Date: Thu Jul 14 2016 - 21:39:26 EST


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.
