From c4e43f5aef9731c480789dcb044d261f894a102e Mon Sep 17 00:00:00 2001 From: Nishanth Menon Date: Tue, 30 May 2023 11:58:57 -0500 Subject: [PATCH] arm64: dts: ti: k3-j7200-mcu: Add mcu_secproxy MCU domain has it's own secure proxy for communicating with ROM and for R5 micro controller firmware operations. This is in addition to the one in the main domain NAVSS subsystem that is used for general purpose communication. Describe the node for use with bootloaders and firmware that require this communication path which uses interrupts to corresponding micro controller interrupt controller. Mark the node as disabled since this instance does not have interrupts routed to the main processor by default for a complete description of the node.
