Disabling ssi removes ssi the error. But the In-Band error is still there, so not related to ssi. I also see these errors: omap_hwmod: mcbsp2_sidetone using broken dt data from mcbsp omap_hwmod: mcbsp3_sidetone using broken dt data from mcbsp omap_hwmod: mcbsp2: cannot be enabled for reset (3) and irq: no irq domain found for /ocp/pinmux@48002030 ! Could these errors also be fixed by the dts.
