Glad and thanks you are doing this. Expectation ofcourse is that we get the dts fixups done and merged asap so that the yaml conversion merges produce a clean dtbs_check - where ever possible hopefully by 5.14-rc1 (I know it is a tall order given the scope of conversion pending - but bite at a time). Jan: Are you OK with this? I think overlays will help introduce the variations you need with the firmware if there is any. > .../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 > -- Regards, Nishanth Menon Key (0xDDB5849D1736249D) / Fingerprint: F8A2 8693 54EB 8232 17A3 1A34 DDB5 849D 1736 249D _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
