From 12df71cd749b9e76c68484a8cedd5347c6679a7b Mon Sep 17 00:00:00 2001 From: Andreas Dannenberg Date: Thu, 25 Apr 2019 12:27:02 -0500 Subject: [PATCH] armv7R: dts: k3: am654: Switch DMSC TX message thread ID Switch from using the high priority DMSC transmit message queue used by the secure R5 MCU island boot context to the low priority message queue. While the change in priority is irrelevant for the current boot architecture it however gives us access to a deeper message queue that will allow us to buffer more messages. This is an important aspect when sending several messages without requesting and waiting for a response in a row which is a communication scheme used during core shutdown for example. See AM654 TISCI User Guide for additional details.
