Since ssi controller is not available on DM3xxx/AM3xxx (AFAIK) it should be disabled for those SoCs: &ssi { status = "disabled"; }; From what I can see the following in-tree .dts files should be fixed, too: * am3517_mt_ventoux.dts Currently includes "omap34xx.dtsi" instead of "am3517.dtsi". Apart from that the following boards seem to use omap36xx.dtsi include, but are actually DM37xx, so they should disable the ssi block: * omap3-igep.dtsi * omap3-lilly-a83x.dtsi * omap3-overo-storm.dtsi I will prepare a patch for that later. -- Sebastian
