TI Wilink 6/7/8 (wl12xx/wl18xx) SDIO devices
|
|
|
|
This node provides properties for controlling the wilink wireless device. The
|
|
node is expected to be specified as a child node to the SDIO controller that
|
|
connects the device to the system.
|
|
|
|
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"
|
|
- interrupts : specifies attributes for the out-of-band interrupt.
|
|
|
|
Optional properties:
|
|
- interrupt-parent : the phandle for the interrupt controller to which the
|
|
device interrupts are connected.
|
|
- ref-clock-frequency : ref clock frequency in Hz
|
|
- tcxo-clock-frequency : tcxo clock frequency in Hz
|
|
|
|
Note: the *-clock-frequency properties assume internal clocks. In case of external
|
|
clock, new bindings (for parsing the clock nodes) have to be added.
|
|
|
|
Example:
|
|
|
|
&mmc3 {
|
|
status = "okay";
|
|
vmmc-supply = <&wlan_en_reg>;
|
|
bus-width = <4>;
|
|
cap-power-off-card;
|
|
keep-power-in-suspend;
|
|
|
|
#address-cells = <1>;
|
|
#size-cells = <0>;
|
|
wlcore: wlcore@2 {
|
|
compatible = "ti,wl1835";
|
|
reg = <2>;
|
|
interrupt-parent = <&gpio0>;
|
|
interrupts = <19 IRQ_TYPE_LEVEL_HIGH>;
|
|
};
|
|
};
