[PATCH v2 2/3] clk: samsung: exynosautov920: add peric1, misc and hsi0/1 clock support

Sunyeal Hong
2024-10-07T08:20:01Z

Register compatible and cmu_info data to support clocks.
CMU_PERIC1, this provides clocks for USI09 ~ USI17, USI_I2C and USI_I3C.
CMU_MISC, this provides clocks for MISC, GIC and OTP.
CMU_HSI0, this provides clocks for PCIE.
CMU_HSI1, this provides clocks for USB and MMC.
