There are no sub-mailbox devices defined currently for both the IOT2050 boards. These are usually dictated by the firmwares running on the R5F remote processors and the applications they provide. Defining the actual sub-mailboxes will also dictate the interrupts the clusters will use for interrupts on the Cortex-A53 cores. Disable all of the Mailbox clusters until the sub-mailboxes are defined and used. This fixes the warnings around the missing interrupts with the upcoming conversion of the OMAP Mailbox binding to YAML format. Signed-off-by: Suman Anna <s-anna@xxxxxx> --- Hi Nishanth, I will be posting the conversion of the OMAP Mailbox binding to YAML sometime next week to deal with the current dtbs_check warnings seen with these nodes on all K3 SoCs. It is kinda of a chicken and egg problem w.r.t when you want all warnings gone, and this is in preparation towards that. It also follows anyway the expected style for Mailbox unless you add the usable mailbox sub-device nodes and the interrupts they use. regards Suman .../boot/dts/ti/k3-am65-iot2050-common.dtsi | 48 +++++++++++++++++++ 1 file changed, 48 insertions(+) diff --git a/arch/arm64/boot/dts/ti/k3-am65-iot2050-common.dtsi b/arch/arm64/boot/dts/ti/k3-am65-iot2050-common.dtsi index de763ca9251c..f4ec9ed52939 100644 --- a/arch/arm64/boot/dts/ti/k3-am65-iot2050-common.dtsi +++ b/arch/arm64/boot/dts/ti/k3-am65-iot2050-common.dtsi @@ -653,3 +653,51 @@ &pcie1_rc { &pcie1_ep { status = "disabled"; }; + +&mailbox0_cluster0 { + status = "disabled"; +}; + +&mailbox0_cluster1 { + status = "disabled"; +}; + +&mailbox0_cluster2 { + status = "disabled"; +}; + +&mailbox0_cluster3 { + status = "disabled"; +}; + +&mailbox0_cluster4 { + status = "disabled"; +}; + +&mailbox0_cluster5 { + status = "disabled"; +}; + +&mailbox0_cluster6 { + status = "disabled"; +}; + +&mailbox0_cluster7 { + status = "disabled"; +}; + +&mailbox0_cluster8 { + status = "disabled"; +}; + +&mailbox0_cluster9 { + status = "disabled"; +}; + +&mailbox0_cluster10 { + status = "disabled"; +}; + +&mailbox0_cluster11 { + status = "disabled"; +}; -- 2.30.1
