An additional register is present in the system controller,
|
||
|
|
which is assumed to be in the same device tree, with and marked
|
||
|
|
as compatible with "cirrus,ep7209-syscon3".
|
||
|
|
|
||
|
|
Example:
|
||
|
|
|
||
|
|
spi@80000500 {
|
||
|
|
#address-cells = <1>;
|
||
|
|
#size-cells = <0>;
|
||
|
|
compatible = "cirrus,ep7209-spi";
|
||
|
|
reg = <0x80000500 0x4>;
|
||
|
|
interrupts = <15>;
|
||
|
|
clocks = <&clks CLPS711X_CLK_SPI>;
|
||
|
|
status = "disabled";
|
||
|
|
};
|
||
|
|
|
||
|
|
syscon3: syscon@80002200 {
|
||
|
|
compatible = "cirrus,ep7209-syscon3", "syscon";
|
||
|
|
reg = <0x80002200 0x40>;
|
