During the conversion, the following updates were made: - Moved the binding to bindings/soc/ti/ - Make the 'ti,hwmods' property optional to resolve dtbs_check warnings, as several in-tree device trees currently omit it. A review of the ti-sysc driver (drivers/bus/ti-sysc.c) shows that the property is not strictly required for probing. The driver only reads it to populate the 'ddata->legacy_mode' flag. If the property is absent, the probe sequence continues normally without error.
