1 Andestech ATCSPI200 SPI controller Device Tree Bindings 2 ------------------------------------------------------- 3 ATCSPI200 is a Serial Peripheral Interface (SPI) controller 4 which serves as a SPI master or a SPI slave. 5 6 It is often be embedded in AE3XX and AE250 platforms. 7 8 Required properties: 9 - compatible: has to be "andestech,atcspi200". 10 - reg: Base address and size of the controllers memory area. 11 - #address-cells: <1>, as required by generic SPI binding. 12 - #size-cells: <0>, also as required by generic SPI binding. 13 - interrupts: Property with a value describing the interrupt number. 14 - clocks: Clock phandles (see clock bindings for details). 15 - spi-max-frequency: Maximum SPI clocking speed of device in Hz. 16 17 Optional properties: 18 - num-cs: Number of chip selects used. 19 20 Example: 21 22 spi: spi@f0b00000 { 23 compatible = "andestech,atcspi200"; 24 reg = <0xf0b00000 0x1000>; 25 #address-cells = <1>; 26 #size-cells = <0>; 27 num-cs = <1>; 28 clocks = <&spiclk>; 29 interrupts = <3 4>; 30 flash@0 { 31 compatible = "spi-flash"; 32 spi-max-frequency = <50000000>; 33 reg = <0>; 34 spi-cpol; 35 spi-cpha; 36 }; 37 }; 38
