This property is equivalent to "disable-wp" defined in Documentation/devicetree/bindings/mmc/tmio_mmc.txt The TMIO MMC core calls mmc_of_parse(), and it sets MMC_CAP2_NO_WRITE_PROTECT if "disable-wp" property is present. We do not need a vendor-specific property to do the same thing. Let's remove the description from the dt-binding to prevent new boards from using it. I am keeping the driver code for existing DT files, but added comments that this is deprecated.
