14*49c04453SDetlev Casanovadescription:
15*49c04453SDetlev Casanova  The RK3576 clock controller generates the clock and also implements a reset
16*49c04453SDetlev Casanova  controller for SoC peripherals. For example it provides SCLK_UART2 and
17*49c04453SDetlev Casanova  PCLK_UART2, as well as SRST_P_UART2 and SRST_S_UART2 for the second UART
18*49c04453SDetlev Casanova  module.
