* Add Clock control module (CCM) support * iMX7D SoC introduces 3 main clock sysmtem abstraction for clock root frequency generation denominated clock slices. Core clock slice: hihg speed clock for ARM core Bus clock slice: for bus clocks IP clock slice: Peripheral clocks * At system boot ROM enables PLL_ARM, PLL_DDR, PLL_SYS, PLL_ENET In u-boot, we have to: - Configure PFD3- PFD7 for freq we needed in u-boot - Set clock root for peripherals (ip channel)
