As a result, dtbs_check reports the following validation errors on the Northstar2 SoC: mmc@66420000 (brcm,sdhci-iproc-cygnus): Unevaluated properties are not allowed ('dma-coherent' was unexpected) mmc@66430000 (brcm,sdhci-iproc-cygnus): Unevaluated properties are not allowed ('dma-coherent' was unexpected) Allow the 'dma-coherent' property in the schema to fix the validation errors and accurately reflect the hardware capability.
