|
||
|
-------------------------------------------
|
||
|
|
||
|
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>;
|
