* Allwinner sun8i system controller
|
||||||
|
|
||||||
|
This file describes the bindings for the system controller present in
|
||||||
|
Allwinner SoC H3, A83T and A64.
|
||||||
|
The principal function of this syscon is to control EMAC PHY choice and
|
||||||
|
config.
|
||||||
|
|
||||||
|
Required properties for the system controller:
|
||||||
|
- reg: address and length of the register for the device.
|
||||||
|
- compatible: should be "syscon" and one of the following string:
|
||||||
|
"allwinner,sun8i-h3-system-controller"
|
||||||
|
"allwinner,sun50i-a64-system-controller"
|
||||||
|
"allwinner,sun8i-a83t-system-controller"
|
||||||
|
|
||||||
|
Example:
|
||||||
|
syscon: syscon@1c00000 {
|
||||||
|
compatible = "allwinner,sun8i-h3-system-controller", "syscon";
|
||||||
|
reg = <0x01c00000 0x1000>;
|
||||||
|
};
