Kernel-4.18.0-80.el8_ti,wl1251

  • Texas Instruments wl1251 wireless lan controller

The wl1251 chip can be connected via SPI or via SDIO. This
document describes the binding for the SPI connected chip.

Required properties:

  • compatible : Should be “ti,wl1251”
  • reg : Chip select address of device
  • spi-max-frequency : Maximum SPI clocking speed of device in Hz
  • interrupts : Should contain interrupt line
  • interrupt-parent : Should be the phandle for the interrupt controller
                    that services interrupts for this device
    
  • vio-supply : phandle to regulator providing VIO
  • ti,power-gpio : GPIO connected to chip’s PMEN pin

Optional properties:

  • ti,wl1251-has-eeprom : boolean, the wl1251 has an eeprom connected, which
                       provides configuration data (calibration, MAC, ...)
    
  • Please consult Documentation/devicetree/bindings/spi/spi-bus.txt
    for optional SPI connection related properties,

Examples:

&spi1 {
wl1251@0 {
compatible = “ti,wl1251”;

    reg = <0>;
    spi-max-frequency = <48000000>;
    spi-cpol;
    spi-cpha;

    interrupt-parent = <&gpio2>;
    interrupts = <10 IRQ_TYPE_NONE>; /* gpio line 42 */

    vio-supply = <&vio>;
    ti,power-gpio = <&gpio3 23 GPIO_ACTIVE_HIGH>; /* 87 */
};

};
