|
Required properties: |
|
|
|
- compatible: Must be "jcore,spi2". |
|
|
|
- reg: Memory region for registers. |
|
|
|
- #address-cells: Must be 1. |
|
|
|
- #size-cells: Must be 0. |
|
|
|
Optional properties: |
|
|
|
- clocks: If a phandle named "ref_clk" is present, SPI clock speed |
|
programming is relative to the frequency of the indicated clock. |

Example: |
|
|
|
spi@40 { |
|
compatible = "jcore,spi2"; |
|
#address-cells = <1>; |
|
#size-cells = <0>; |
|
reg = <0x40 0x8>; |
|
spi-max-frequency = <25000000>; |
|
clocks = <&bus_clk>; |
|
clock-names = "ref_clk"; |
|
}
