From: Yang Xiwen <forbidden405@xxxxxxxxxxx>
Also rename to hisilicon,hisi-crg.yaml. While at it, add "syscon" and
"simple-mfd" compatibles to match the existing hi3798cv200.dtsi.
Add reset-controller subnode for hisilicon,hi3798cv200-crg to match the
existing hi3798cv200.dtsi.

-* HiSilicon Clock and Reset Generator(CRG)
-
-The CRG module provides clock and reset signals to various
-modules within the SoC.
-
-This binding uses the following bindings:
- Documentation/devicetree/bindings/clock/clock-bindings.txt
- Documentation/devicetree/bindings/reset/reset.txt
-
-Required Properties:
-
-- compatible: should be one of the following.
- - "hisilicon,hi3516cv300-crg"
- - "hisilicon,hi3516cv300-sysctrl"
- - "hisilicon,hi3519-crg"
- - "hisilicon,hi3798cv200-crg"
- - "hisilicon,hi3798cv200-sysctrl"
-
-- reg: physical base address of the controller and length of memory mapped
- region.
-
-- #clock-cells: should be 1.
-
-Each clock is assigned an identifier and client nodes use this identifier
-to specify the clock which they consume.
-
-All these identifier could be found in <dt-bindings/clock/hi3519-clock.h>.
-
-- #reset-cells: should be 2.
-
-A reset signal can be controlled by writing a bit register in the CRG module.
-The reset specifier consists of two cells. The first cell represents the
-register offset relative to the base address. The second cell represents the
-bit index in the register.
-
-Example: CRG nodes
-CRG: clock-reset-controller@12010000 {
- compatible = "hisilicon,hi3519-crg";
- reg = <0x12010000 0x10000>;
- #clock-cells = <1>;
- #reset-cells = <2>;
-};
-
-Example: consumer nodes
-i2c0: i2c@12110000 {
- compatible = "hisilicon,hi3519-i2c";
- reg = <0x12110000 0x1000>;
- clocks = <&CRG HI3519_I2C0_RST>;
- resets = <&CRG 0xe4 0>;
-};
