Andestech ATCSPI200 SPI controller Device Tree Bindings
|
|
-------------------------------------------------------
|
|
ATCSPI200 is a Serial Peripheral Interface (SPI) controller
|
|
which serves as a SPI master or a SPI slave.
|
|
|
|
It is often be embedded in AE3XX and AE250 platforms.
|
|
|
|
Required properties:
|
|
- compatible: has to be "andestech,atcspi200".
|
|
- reg: Base address and size of the controllers memory area.
|
|
- #address-cells: <1>, as required by generic SPI binding.
|
|
- #size-cells: <0>, also as required by generic SPI binding.
|
|
- interrupts: Property with a value describing the interrupt number.
|
|
- clocks: Clock phandles (see clock bindings for details).
|
|
- spi-max-frequency: Maximum SPI clocking speed of device in Hz.
|
|
|
|
Optional properties:
|
|
- num-cs: Number of chip selects used.
|
|
|
|
Example:
|
|
|
|
spi: spi@f0b00000 {
|
|
compatible = "andestech,atcspi200";
|
|
reg = <0xf0b00000 0x1000>;
|
|
#address-cells = <1>;
|
|
#size-cells = <0>;
|
|
num-cs = <1>;
|
|
clocks = <&spiclk>;
|
|
interrupts = <3 4>;
|
|
flash@0 {
|
|
compatible = "jedec,spi-nor";
|
|
spi-max-frequency = <50000000>;
|
|
reg = <0>;
|
|
spi-cpol;
|
|
spi-cpha;
|
|
};
|
|
};
