Subject: [PATCH v3 04/12] dt-bindings: misc: add property to support non-secure DSP
Date: Wed, 26 Jan 2022 13:52:56 +0000 [thread overview]
Message-ID: <20220126135304.16340-5-srinivas.kandagatla@linaro.org> (raw)
In-Reply-To: <20220126135304.16340-1-srinivas.kandagatla@linaro.org>
From: Jeya R <jeyr@codeaurora.org>
Add property to set DSP domain as non-secure.
ADSP/MDSP/SDSP are by default secured, where as CDSP can be either be
secured/unsecured.
non-secured Compute DSP would allow users to load unsigned process
and run hexagon instructions, but limiting access to secured hardware
within the DSP.
Based on this flag device nodes for secured and unsecured are created.
