1 | Cadence SPI controller Device Tree Bindings |
2 | ------------------------------------------- | |
3 | ||
4 | Required properties: | |
5 | - compatible : Should be "cdns,spi-r1p6" or "xlnx,zynq-spi-r1p6". | |
6 | - reg : Physical base address and size of SPI registers map. | |
7 | - interrupts : Property with a value describing the interrupt | |
8 | number. | |

9 | - clock-names : List of input clock names - "ref_clk", "pclk" |
10 | (See clock bindings for details). | |
11 | - clocks : Clock phandles (see clock bindings for details). | |
12 | ||
13 | Optional properties: | |
14 | - num-cs : Number of chip selects used. | |
15 | If a decoder is used, this will be the number of | |
16 | chip selects after the decoder. | |
17 | - is-decoded-cs : Flag to indicate whether decoder is used or not. | |
18 | ||
19 | Example: | |
20 | ||
21 | spi@e0007000 { | |
22 | compatible = "xlnx,zynq-spi-r1p6"; | |
23 | clock-names = "ref_clk", "pclk"; | |
24 | clocks = <&clkc 26>, <&clkc 35>; | |
25 | interrupt-parent = <&intc>; | |
26 | interrupts = <0 49 4>; | |
27 | num-cs = <4>; | |
28 | is-decoded-cs = <0>; | |
29 | reg = <0xe0007000 0x1000>; | |
30 | } ; |
