Atmel SPI device
|
|
|
|
Required properties:
|
|
- compatible : should be "atmel,at91rm9200-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>;
