Cadence SPI controller Device Tree Bindings |
|
------------------------------------------- |
|
|
|
Required properties: |
|
- compatible : Should be "cdns,spi-r1p6" or "xlnx,zynq-spi-r1p6". |
|
- reg : Physical base address and size of SPI registers map. |
|
- interrupts : Property with a value describing the interrupt |
|
number. |
|
- clock-names : List of input clock names - "ref_clk", "pclk" |
|
(See clock bindings for details). |
|
- clocks : Clock phandles (see clock bindings for details). |
|
|
|
Optional properties: |
|
- num-cs : Number of chip selects used. |
|
If a decoder is used, this will be the number of |
|
chip selects after the decoder. |
|
- is-decoded-cs : Flag to indicate whether decoder is used or not. |
|
|
|
Example: |
|
|
|
spi@e0007000 { |
|
compatible = "xlnx,zynq-spi-r1p6"; |
|
clock-names = "ref_clk", "pclk"; |
|
clocks = <&clkc 26>, <&clkc 35>; |
|
interrupt-parent = <&intc>; |
|
interrupts = <0 49 4>; |
|
num-cs = <4>; |
|
is-decoded-cs = <0>; |
|
reg = <0xe0007000 0x1000>; |
|
} ;
