st,stm32-spi-fifo¶

Description¶

These nodes are “spi” bus nodes.

STM32 SPI controller with embedded Rx and Tx FIFOs

Properties¶

Properties not inherited from the base binding file.

Name

Type

Details

pinctrl-0

phandles

Pin configuration for SPI signals (MISO, MOSI, SCK and optional NSS).
We expect that the phandles will reference pinctrl nodes.

For example the SPI3 would be
   <&spi3_sck_pc10 &spi3_miso_pc11 &spi3_mosi_pc12>;

Example with NSS Pin
   <&spi3_sck_pc10 &spi3_miso_pc11 &spi3_mosi_pc12 &spi3_nss_pa15>;

clock-frequency

int

Clock frequency the SPI peripheral is being driven at

cs-gpios

phandle-array

Properties inherited from the base binding file, which defines common properties that may be set on many nodes. Not all of these may apply to the “st,stm32-spi-fifo” compatible.
