Keeping the vendor specific ti,ssc-deltam, ti,ssc-modfreq-hz and ti,ssc-downspread properties would leave two ways to describe the same thing. The properties have no in-tree users, so they can be dropped. Existing DTS files using them continue to work, with SSC disabled, until they switch to assigned-clock-sscs. Signed-off-by: Dario Binacchi --- If keeping the properties as deprecated is preferred, I can add a fallback to the driver in v2.
