Subject: [PATCH v1 1/2] dt/bindings: add bindings for optional optee rng-uuid property
Date: Thu, 27 Dec 2018 16:37:10 +0530 [thread overview]
Message-ID: <1545908831-25910-2-git-send-email-sumit.garg@linaro.org> (raw)
In-Reply-To: <1545908831-25910-1-git-send-email-sumit.garg@linaro.org>
Add bindings for OP-TEE based optional hardware random number
generator identifier property. It could be used on ARM based devices
where entropy source is not accessible to normal world (linux in this
case).
