1 TI Wilink 6/7/8 (wl12xx/wl18xx) SDIO devices
2
3 This node provides properties for controlling the wilink wireless device. The
4 node is expected to be specified as a child node to the SDIO controller that
5 connects the device to the system.
6
7 Required properties:
8  - compatible: should be one of the following:
9     * "ti,wl1271"
10     * "ti,wl1273"
11     * "ti,wl1281"
12     * "ti,wl1283"
13     * "ti,wl1801"
14     * "ti,wl1805"
15     * "ti,wl1807"
16     * "ti,wl1831"
17     * "ti,wl1835"
18     * "ti,wl1837"
19  - interrupts : specifies attributes for the out-of-band interrupt.
20
21 Optional properties:
22  - interrupt-parent : the phandle for the interrupt controller to which the
23         device interrupts are connected.
24  - ref-clock-frequency : ref clock frequency in Hz
25  - tcxo-clock-frequency : tcxo clock frequency in Hz
26
27 Note: the *-clock-frequency properties assume internal clocks. In case of external
28 clock, new bindings (for parsing the clock nodes) have to be added.

30 Example:
31
32 &mmc3 {
33         status = "okay";
34         vmmc-supply = <&wlan_en_reg>;
35         bus-width = <4>;
36         cap-power-off-card;
37         keep-power-in-suspend;
38
39         #address-cells = <1>;
40         #size-cells = <0>;
41         wlcore: wlcore@2 {
42                 compatible = "ti,wl1835";
43                 reg = <2>;
44                 interrupt-parent = <&gpio0>;
45                 interrupts = <19 IRQ_TYPE_LEVEL_HIGH>;
46         };
