[PATCH v2] ASoC: dt-bindings: fsl,ssi: Convert to YAML
Convert the fsl,ssi binding to YAML. Add below compatible strings which were not listed in document: fsl,imx50-ssi fsl,imx53-ssi fsl,imx25-ssi fsl,imx27-ssi fsl,imx6q-ssi fsl,imx6sl-ssi fsl,imx6sx-ssi Add below fsl,mode strings which were not listed. i2s-slave i2s-master lj-slave lj-master rj-slave rj-master Add 'ac97-gpios' property which were not listed. Then dtbs_check can pass. And remove the 'codec' description which should be in the 'codec' binding doc.
