Subject: [PATCH] dt-bindings: add device tree binding for Allwinner XR819 SDIO Wi-Fi
Date: Tue, 18 Jul 2017 15:29:40 +0800 [thread overview]
Message-ID: <20170718072940.17872-1-icenowy@aosc.io> (raw)
Allwinner XR819 is a SDIO Wi-Fi chip, which has the functionality to use
an out-of-band interrupt pin instead of SDIO in-band interrupt.
Add the device tree binding of this chip, in order to make it possible
to add this interrupt pin to device trees.

+Allwinner XRadio wireless SDIO devices
+
+This node provides properties for controlling the XRadio 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 "allwinner,xr819".
+
+Optional properties:
+ - interrupt-parent : the phandle for the interrupt controller to which the
+ device interrupts are connected.
+ - interrupts : specifies attributes for the out-of-band interrupt (host-wake).
+ When not specified the device will use in-band SDIO interrupts.
+
+Example:
+
+mmc1: mmc@01c10000 {
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ pinctrl-names = "default";
+ pinctrl-0 = <&mmc1_pins_a>;
+ vmmc-supply = <®_vcc_wifi>;
+ mmc-pwrseq = <&wifi_pwrseq>;
+ bus-width = <4>;
+ non-removable;
+ status = "okay";
+
+ xr819: sdio_wifi@1 {
+ reg = <1>;
+ compatible = "allwinner,xr819";
+ interrupt-parent = <&pio>;
+ interrupts = <6 10 IRQ_TYPE_EDGE_RISING>;
+ };
+};
