Kernel-4.18.0-80.el8_spi-lantiq-ssc

Lantiq Synchronous Serial Controller (SSC) SPI master driver

Required properties:

  • compatible: “lantiq,ase-spi”, “lantiq,falcon-spi”, “lantiq,xrx100-spi”
  • #address-cells: see spi-bus.txt
  • #size-cells: see spi-bus.txt
  • reg: address and length of the spi master registers
  • interrupts: should contain the “spi_rx”, “spi_tx” and “spi_err” interrupt.

Optional properties:

  • clocks: spi clock phandle
  • num-cs: see spi-bus.txt, set to 8 if unset
  • base-cs: the number of the first chip select, set to 1 if unset.

Example:

spi: spi@e100800 {
compatible = “lantiq,xrx200-spi”, “lantiq,xrx100-spi”;
reg = <0xE100800 0x100>;
interrupt-parent = <&icu0>;
interrupts = <22 23 24>;
interrupt-names = “spi_rx”, “spi_tx”, “spi_err”;
#address-cells = <1>;
#size-cells = <1>;
num-cs = <6>;
base-cs = <1>;
};
