Atmel SPI device |
|
|
|
Required properties: |
|
- compatible : should be "atmel,at91rm9200-spi" or "microchip,sam9x60-spi". |
|
- reg: Address and length of the register set for the device |
|
- interrupts: Should contain spi interrupt |
|
- cs-gpios: chipselects (optional for SPI controller version >= 2 with the |
|
Chip Select Active After Transfer feature). |
|
- clock-names: tuple listing input clock names. |
|
Required elements: "spi_clk" |
|
- clocks: phandles to input clocks. |
|
|
|
Optional properties: |
|
- atmel,fifo-size: maximum number of data the RX and TX FIFOs can store for FIFO |
|
capable SPI controllers. |
|
|
|
Example: |
|
|
|
spi1: spi@fffcc000 { |
|
compatible = "atmel,at91rm9200-spi"; |
|
reg = <0xfffcc000 0x4000>; |
|
interrupts = <13 4 5>; |
|
#address-cells = <1>; |
|
#size-cells = <0>; |
|
clocks = <&spi1_clk>; |
|
clock-names = "spi_clk"; |
|
cs-gpios = <&pioB 3 0>; |
|
atmel,fifo-size = <32>; |
|
|
|
mmc-slot@0 { |
|
compatible = "mmc-spi-slot"; |
|
reg = <0>; |
|
gpios = <&pioC 4 0>; /* CD */ |
|
spi-max-frequency = <25000000>; |
|
}; |
