We introduce new PLL register APIs and some helpers for FHCTL hardware control. For MT8186 PLL driver, we replace mtk_clk_register_plls() with newly added API to support frequency hopping and SSC function for specific PLLs. Changes in v4: - Fixup iospace error in the binding. - Use GENMASK marco and remove extra line. Changes in v3: - Change binding file name. - Add some constraints for properties. - Rename "mediatek,hopping-ssc-percents" to "mediatek,hopping-ssc-percent". - Add new config symbol. Changes in v2: - Use SoC-specific compatible instead of generic one. - Use standard clocks property and vendor-specific property in dt-binding. - Remove some unused arguments and fix some coding style.
