Changes during Conversion: - Define new properties like "clocks", "clock-names", "pbias-supply" and "power-domains" to resolve dtb_check errors. - Remove "pinctrl-names" and "pinctrl-" from required as they are not necessary for all DTS files. - Remove "ti,hwmods" property entirely from the YAML as the DTS doesn't contain this property for the given compatibles and the text binding is misleading. - Add "clocks", "clock-names" and "max-frequency" to the required properties based on the compatible and the text binding doesn't mention these properties as required. - Add missing strings like "default-rev11", "sdr12-rev11", "sdr25-rev11", "hs-rev11", "sdr25-rev11" and "sleep" to pinctrl-names string array to resolve errors detected by dtb_check.
