Sean Anderson f9c7d4f99f clk: Add K210 clock support
Due to the large number of clocks, I decided to use the CCF. The overall
structure is modeled after the imx code. Clocks parameters are stored in
several arrays, and are then instantiated at run-time. There are some
translation macros (FOOIFY()) which allow for more dense packing.

Kendryte K210 Sysctl
This binding describes the K210 sysctl device, which contains many miscellaneous
registers controlling system functionality. This node is a register map and can
be reference by other bindings which need a phandle to the K210 sysctl regmap.
Required properties:
- compatible: should be
"kendryte,k210-sysctl", "syscon", "simple-mfd"
- reg: address and length of the sysctl registers
- reg-io-width: must be <4>
Clock sub-node
This node is a binding for the clock tree driver
Required properties:
- compatible: should be "kendryte,k210-clk"
- clocks: phandle to the "in0" external oscillator
- #clock-cells: must be <1>
Example:
sysctl: syscon@50440000 {
compatible = "kendryte,k210-sysctl", "syscon", "simple-mfd";
reg = <0x50440000 0x100>;
reg-io-width = <4>;
sysclk: clock-controller {
compatible = "kendryte,k210-clk";
clocks = <&in0>;
#clock-cells = <1>;
};
};
