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 --- diff --git a/arch/arm/boot/dts/st/stm32mp15xx-dhcor-som.dtsi b/arch/arm/boot/dts/st/stm32mp15xx-dhcor-som.dtsi index bba19f21e527..89881a26c614 100644 --- a/arch/arm/boot/dts/st/stm32mp15xx-dhcor-som.dtsi +++ b/arch/arm/boot/dts/st/stm32mp15xx-dhcor-som.dtsi @@ -227,8 +227,8 @@ &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>; status = "okay";
