Exynos ISP SPI Subsystem
|
||
|
|
|
||
|
|
The device node for ISP SPI subsytem.
|
||
|
|
Since Peripheral id in EXYNOS is decoded based on Interrupts, currently
|
||
|
|
ISP SPI have no individual interrupts hence we add ad dummy interrupt node
|
||
|
|
which will have a value beyond the maximum number of interrupts exynos5 can
|
||
|
|
support.
|
||
|
|
|
||
|
|
Required properties :
|
||
|
|
- compatible : Should be "samsung,exynos-spi" for spi.
|
||
|
|
- reg : Base adrress of the the subsystem.
|
||
|
|
- interrupts : A value which is beyond the maximum number of interrupts
|
||
|
|
exynos5 can support.
|
||
|
|
|
||
|
|
Example:
|
||
|
|
spi@131a0000 {
|
||
|
|
#address-cells = <1>;
|
||
|
|
#size-cells = <0>;
|
||
|
|
compatible = "samsung,exynos-spi";
|
||
|
|
reg = <0x131a0000 0x30>;
|
||
|
|
interrupts = <0 129 0>;
|
||
|
|
};
