| | | | | | | | | | | GPLL like the Linux kernel does. Use NPLL for the CPU clock such that adjusting the CPU frequency doesn't change the clock of other devices anymore. Implement the last clocks that are used in the assigned-clocks property of clock controller. Don't enable the assigned-clocks processing yet as it results in a sub-optimal clock for for the SD and eMMC controllers. This clock handling in dwmcc(4) needs some further work before we can enable this.

| | | | | | | | | | each and every clock, use a data structure for each clock and generic code that handles muxing and clock division based on that data structure. This should reduce the amount of code and hopefully make the process of adding clocks less error prone as it is easy to check the data structures against the SoC documentation. This approach will be used for the other Rockchip SoCs in the future as well.

| | | | | | | | | | | of the clocks that we can set. Assign clock rates (and parents) based on the "assigned-clocks" device tree property, but only on RK3399 for now as the code for the other Rockchip SoCs isn't quite ready yet. Last but not least, fixup a mistake on the firmware for the Theobroma Systems RK3399-Q7 module such that the "big" cluster uses BPLL as intended.
