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.
