Commit Message

Sunyeal Hong Oct. 7, 2024, 7:18 a.m. UTC 
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.
