From 0ee0ef38aa9f75f21b51f729dd42b2e932515188 Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Thu, 18 May 2023 03:12:42 +0200 Subject: [PATCH] ARM: dts: stm32: Add missing detach mailbox for emtrion emSBC-Argon Add missing "detach" mailbox to this board to permit the CPU 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. Without this mailbox, detach is not possible and kernel log contains the following warning to, so make sure all the STM32MP15xx platform DTs are in sync regarding the mailboxes to fix the detach issue and the warning: " stm32-rproc 10000000.m4: mbox_request_channel_byname() could not locate channel named "detach" " Fixes: 6257dfc1c412 ("ARM: dts: stm32: Add coprocessor detach mbox on stm32mp15x-dkx boards") Signed-off-by: Marek Vasut Signed-off-by: Alexandre Torgue --- arch/arm/boot/dts/st/stm32mp157c-emstamp-argon.dtsi | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/arch/arm/boot/dts/st/stm32mp157c-emstamp-argon.dtsi b/arch/arm/boot/dts/st/stm32mp157c-emstamp-argon.dtsi index 94e38141af67..fd89542c69c9 100644 --- a/arch/arm/boot/dts/st/stm32mp157c-emstamp-argon.dtsi +++ b/arch/arm/boot/dts/st/stm32mp157c-emstamp-argon.dtsi @@ -368,8 +368,8 @@ &m4_rproc { memory-region = <&retram>, <&mcuram>, <&mcuram2>, <&vdev0vring0>, <&vdev0vring1>, <&vdev0buffer>; - mboxes = <&ipcc 0>, <&ipcc 1>, <&ipcc 2>; - mbox-names = "vq0", "vq1", "shutdown"; + mboxes = <&ipcc 0>, <&ipcc 1>, <&ipcc 2>, <&ipcc 3>; + mbox-names = "vq0", "vq1", "shutdown", "detach"; interrupt-parent = <&exti>; interrupts = <68 1>; interrupt-names = "wdg"; -- 2.11.0
