Kernel-4.18.0-80.el8_ti,wlcore,spi

• Texas Instruments wl12xx/wl18xx wireless lan controller

The wl12xx/wl18xx chips can be connected via SPI or via SDIO. This
document describes the binding for the SPI connected chip.

Required properties:

• compatible : Should be one of the following:
  • “ti,wl1271”
  • “ti,wl1273”
  • “ti,wl1281”
  • “ti,wl1283”
  • “ti,wl1801”
  • “ti,wl1805”
  • “ti,wl1807”
  • “ti,wl1831”
  • “ti,wl1835”
  • “ti,wl1837”
• reg : Chip select address of device
• spi-max-frequency : Maximum SPI clocking speed of device in Hz
• interrupt-parent, interrupts :

                    Should contain parameters for 1 interrupt line.
                    Interrupt parameters: parent, line number, type.
  

• vwlan-supply : Point the node of the regulator that powers/enable the

                    wl12xx/wl18xx chip
  

Optional properties:

• ref-clock-frequency : Reference clock frequency (should be set for wl12xx)

• clock-xtal : boolean, clock is generated from XTAL

• Please consult Documentation/devicetree/bindings/spi/spi-bus.txt
  for optional SPI connection related properties,

Examples:

For wl12xx family:
&spi1 {
wlcore: wlcore@1 {
compatible = “ti,wl1271”;
reg = <1>;
spi-max-frequency = <48000000>;
interrupt-parent = <&gpio3>;
interrupts = <8 IRQ_TYPE_LEVEL_HIGH>;
vwlan-supply = <&vwlan_fixed>;
clock-xtal;
ref-clock-frequency = <38400000>;
};
};

For wl18xx family:
&spi0 {
wlcore: wlcore@0 {
compatible = “ti,wl1835”;
reg = <0>;
spi-max-frequency = <48000000>;
interrupt-parent = <&gpio0>;
interrupts = <27 IRQ_TYPE_EDGE_RISING>;
vwlan-supply = <&vwlan_fixed>;
};
};
