Damien Le Moal fd426b3106 k210: use the board vendor name rather than the marketing name
"kendryte" is the marketing name for the K210 RISC-V SoC produced by
Canaan Inc. Rather than "kendryte,k210", use the usual "canaan,k210"
vendor,SoC compatibility string format in the device tree files and
use the SoC name for file names.
With these changes, the device tree files are more in sync with the
Linux kernel DTS and drivers, making uboot device tree usable by the
kernel.

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
"canaan,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 "canaan,k210-clk"
- clocks: phandle to the "in0" external oscillator
- #clock-cells: must be <1>
Example:
sysctl: syscon@50440000 {
compatible = "canaan,k210-sysctl", "syscon", "simple-mfd";
reg = <0x50440000 0x100>;
reg-io-width = <4>;
sysclk: clock-controller {
compatible = "canaan,k210-clk";
clocks = <&in0>;
#clock-cells = <1>;
};
};
