From 19f969c0c7388a729ec209ff74590c65a1957aab Mon Sep 17 00:00:00 2001 From: =?utf8?q?Leonard=20G=C3=B6hrs?= Date: Fri, 10 Mar 2023 10:26:50 +0100 Subject: [PATCH] ARM: dts: stm32: Add coprocessor detach mbox on stm32mp15xx-osd32 SoM MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit 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. See 6257dfc1c412dcdbd76ca5fa92c8444222dbe5b0 for a patch that does the same for stm32mp15x-dkx boards.
