Series clk: ti: dpll: switch spread spectrum to the generic framework |

Commit Message

Dario Binacchi Oct. 28, 2026, 7:44 a.m. UTC 
The common clock binding provides assigned-clock-sscs to configure
spread spectrum clocking (SSC), supported by the clock core since commit
a7f16660af39 ("clk: conf: Support assigned-clock-sscs"). Deprecate the
vendor specific ti,ssc-deltam, ti,ssc-modfreq-hz and ti,ssc-downspread
properties in favor of it, so that new DTs use a single way to describe
the same thing.

Changes in v3:
- Deprecate the properties instead of dropping them
