If anyone has any objections, please let me know. ------------------ From: Marek Vasut [ Upstream commit 966f04a89d77548e673de2c400abe0b2cf5c15db ] 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 Signed-off-by: Sasha Levin --- arch/arm/boot/dts/stm32mp157c-odyssey-som.dtsi | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/arch/arm/boot/dts/stm32mp157c-odyssey-som.dtsi b/arch/arm/boot/dts/stm32mp157c-odyssey-som.dtsi index e22871dc580c8..cf74852514906 100644 --- a/arch/arm/boot/dts/stm32mp157c-odyssey-som.dtsi +++ b/arch/arm/boot/dts/stm32mp157c-odyssey-som.dtsi @@ -230,8 +230,8 @@ &iwdg2 { &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"; -- 2.40.1
