[PATCH v4 4/6] dt-bindings: crypto: Add new compatible qcom,prng-ee

From: Vinod Koul <vkoul@kernel.org>
Date: 2018-07-04 11:45:26
Also in: linux-arm-msm, lkml
Subsystem: arm/qualcomm mailing list, crypto api, open firmware and flattened device tree bindings, the rest · Maintainers: Herbert Xu, "David S. Miller", Rob Herring, Krzysztof Kozlowski, Conor Dooley, Linus Torvalds

Later qcom chips support v2 of the prng, which exposes an EE
(Execution Environment) for OS to use so add new compatible
qcom,prng-ee for this.
