PLL and dividers used for CPU and some sort of BUS. * SYSC_REG_CPLL_CLKCFG1 - a banch of gates to enable/disable clocks for all or some ip cores. Looking into driver code, and some openWRT patched there are another frequencies which are used in some drivers (uart, sd...). According to all of this information the clock plan for this SoC is set as follows: - Main top clock "xtal" from where all the rest of the world is derived. - CPU clock "cpu" derived from "xtal" frequencies and a bunch of register reads and predividers. - BUS clock "bus" derived from "cpu" and with (cpu / 4) MHz. - Fixed clocks from "xtal": * "50m": 50 MHz. * "125m": 125 MHz. * "150m": 150 MHz. * "250m": 250 MHz. * "270m": 270 MHz. We also have a buch of gate clocks with their parents: * "hsdma": "150m" * "fe": "250m" * "sp_divtx": "270m" * "timer": "50m" * "pcm": "270m" * "pio": "50m" * "gdma": "bus" * "nand": "125m" * "i2c": "50m" * "i2s": "270m" * "spi": "bus" * "uart1": "50m" * "uart2": "50m" * "uart3": "50m" * "eth": "50m" * "pcie0": "125m" * "pcie1": "125m" * "pcie2": "125m" * "crypto": "250m" * "shxc": "50m" With this information the clk driver will provide clock and gates functionality from a a set of hardcoded clocks allowing to define a nice device tree without fixed clocks.
