* Energy Micro EFM32 SPI |
|
|
|
Required properties: |
|
- #address-cells: see spi-bus.txt |
|
- #size-cells: see spi-bus.txt |
|
- compatible: should be "energymicro,efm32-spi" |
|
- reg: Offset and length of the register set for the controller |
|
- interrupts: pair specifying rx and tx irq |
|
- clocks: phandle to the spi clock |
|
- cs-gpios: see spi-bus.txt |
|
|
|
Recommended properties : |
|
- energymicro,location: Value to write to the ROUTE register's LOCATION |
|
bitfield to configure the pinmux for the device, see |
|
datasheet for values. |
|
If this property is not provided, keeping what is |
|
already configured in the hardware, so its either the |
|
reset default 0 or whatever the bootloader did. |
|
|
|
Example: |
|
|
|
spi1: spi@4000c400 { /* USART1 */ |
|
#address-cells = <1>; |
|
#size-cells = <0>; |
|
compatible = "energymicro,efm32-spi"; |
|
reg = <0x4000c400 0x400>; |
|
interrupts = <15 16>; |
|
clocks = <&cmu 20>; |
|
cs-gpios = <&gpio 51 1>; // D3 |
|
energymicro,location = <1>; |
|
|
|
ks8851@0 { |
|
compatible = "ks8851"; |
|
spi-max-frequency = <6000000>; |
|
reg = <0>; |
|
interrupt-parent = <&boardfpga>; |
|
interrupts = <4>; |
|
}; |
|
};
