|
configuring elements such as clocks, pinmux, and reset.
|
|
|
|

|
|
- compatible: One of:
|
|
"aspeed,ast2400-scu", "syscon", "simple-mfd"
|
|
"aspeed,g4-scu", "syscon", "simple-mfd"
|
|
"aspeed,ast2500-scu", "syscon", "simple-mfd"
|
|
"aspeed,g5-scu", "syscon", "simple-mfd"
|
|
|
|
- reg: contains the offset and length of the SCU memory region
|
|
- #clock-cells: should be set to <1> - the system controller is also a
|
|
clock provider
|
|
- #reset-cells: should be set to <1> - the system controller is also a
|
|
reset line provider
|
|
|
|
Example:
|
|
|
|
syscon: syscon@1e6e2000 {
|
|
compatible = "aspeed,ast2400-scu", "syscon", "simple-mfd";
|
|
reg = <0x1e6e2000 0x1a8>;
|
|
#clock-cells = <1>;
|
|
#reset-cells = <1>;
|
|
};
