From 77f622cb8633c020a78cfb8b7d3d73ba3eaf0a44 Mon Sep 17 00:00:00 2001 From: Nishanth Menon Date: Tue, 30 May 2023 11:58:59 -0500 Subject: [PATCH] arm64: dts: ti: k3-j721s2-mcu-wakeup: Add sa3_secproxy and mcu_sec_proxy Security Management Subsystem(SMS) has it's own unique secure proxy as part of Security Accelerator (SA3) module. This is used for communicating with ROM and for special usecases such as HSM operations. In addition MCU island has it's own secure proxy for usecases involving the MCU micro controllers. These are in addition to the one in the main domain DMSS subsystem that is used for general purpose communication. Describe the nodes for use with bootloaders and firmware that require these communication paths which uses interrupts to corresponding micro controller interrupt controller. Mark the node as disabled since these instances do not have interrupts routed to the main processor by default for a complete description of the node.
