Add device node for it. Although the Wi-Fi module is an external module which should be inserted to a header, according to my personal talk with TL Lim, he does not want this header to be used as GPIO (so it's with 2.0mm pitch, not 2.54mm as other GPIO headers). Signed-off-by: Icenowy Zheng --- Changes in v3: - Added explaination on 2.0mm pitch. arch/arm64/boot/dts/allwinner/sun50i-a64-pine64.dts | 16 ++++++++++++++++ 1 file changed, 16 insertions(+) diff --git a/arch/arm64/boot/dts/allwinner/sun50i-a64-pine64.dts b/arch/arm64/boot/dts/allwinner/sun50i-a64-pine64.dts index 7da074f95065..9d90bb32aa87 100644 --- a/arch/arm64/boot/dts/allwinner/sun50i-a64-pine64.dts +++ b/arch/arm64/boot/dts/allwinner/sun50i-a64-pine64.dts @@ -64,6 +64,11 @@ regulator-min-microvolt = <3300000>; regulator-max-microvolt = <3300000>; }; + + wifi_pwrseq: wifi_pwrseq { + compatible = "mmc-pwrseq-simple"; + reset-gpios = <&r_pio 0 2 GPIO_ACTIVE_LOW>; /* PL2 */ + }; }; &ehci1 { @@ -91,6 +96,17 @@ status = "okay"; }; +&mmc1 { + pinctrl-names = "default"; + pinctrl-0 = <&mmc1_pins>; + vmmc-supply = <®_dldo4>; + vqmmc-supply = <®_eldo1>; + mmc-pwrseq = <&wifi_pwrseq>; + non-removable; + bus-width = <4>; + status = "okay"; +}; + &ohci1 { status = "okay"; }; -- 2.12.2
