From 9542ca9e9a99ac9fa6103816bf356a3216df8f1b Mon Sep 17 00:00:00 2001 From: Arnaud Pouliquen Date: Mon, 14 Jun 2021 18:49:39 +0200 Subject: ARM: dts: stm32: Add coprocessor detach mbox on stm32mp157c-ed1 board To support the detach feature, add a new mailbox channel to inform the remote processor on a detach. This signal allows the remote processor firmware to stop IPC communication and to reinitialize the resources for a re-attach.
