Introduce DT properties 'realtek,clkout-ssc-enable', 'realtek,rxc-ssc-enable' and 'realtek,sysclk-ssc-enable' which control CLKOUT, RXC and SYSCLK SSC spread spectrum clocking enablement on these signals. These clock are not exposed via the clock API, therefore assigned-clock-sscs property does not apply. Reviewed-by: Krzysztof Kozlowski Signed-off-by: Marek Vasut --- Cc: "David S.
