Subject: [PATCH v2 0/2] add optional cache params override from DT

Rework the setting of cache parameters, including
optionally allowing overiding the defaults from device tree

Changes from v1:
- As per Rob Herring's suggestions, lose the distinction between
read and write and limit options to a few that make sense.
Also use strings to make the meaning of the setting clearer.

Gilad Ben-Yossef (2):
dt-bindings: crypto: update ccree optional params
crypto: ccree - add custom cache params from DT file
