If anyone has any objections, please let me know. ------------------ From: Marek Vasut [ Upstream commit deb7edbc27a6ec4d8f5edfd8519b7ed13cbd2a52 ] 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/st/stm32mp15xx-dhcom-som.dtsi | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/arch/arm/boot/dts/st/stm32mp15xx-dhcom-som.dtsi b/arch/arm/boot/dts/st/stm32mp15xx-dhcom-som.dtsi index e61df23d361a7..74a11ccc5333f 100644 --- a/arch/arm/boot/dts/st/stm32mp15xx-dhcom-som.dtsi +++ b/arch/arm/boot/dts/st/stm32mp15xx-dhcom-som.dtsi @@ -416,8 +416,8 @@ &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
