Convert existing binding to dtschema to support validation. The 'fsl,imx28-rtc' compatible is currently not supported, and it is only referenced in this binding and in nxp/mxs/imx28.dtsi. Therefore, that compatible has been dropped, which triggers a warning when testing the DT against the new binding. There is another reference to fsl,stmp3xxx-rtc in nxp/mxs/imx23.dtsi, where another unsupported compatible 'fsl,imx23-rtc' is used, and the same problem would arise when testing the file against the new binding.
