mh I guess your board's dts included omap36xx.dtsi or omap34xx.dtsi.
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.
