From fb42387b2e46cd2b1a5aee9a8c7ffc6eaf2df4eb Mon Sep 17 00:00:00 2001 From: Jeya R Date: Mon, 14 Feb 2022 16:09:54 +0000 Subject: [PATCH] dt-bindings: misc: add property to support non-secure DSP 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.
