From 15ede97054889c0bec09f1f9b71beffecf06fc67 Mon Sep 17 00:00:00 2001 From: Ondrej Jirman Date: Fri, 23 Aug 2019 11:42:28 +0200 Subject: [PATCH] arm64: dts: allwinner: orange-pi-3: Enable WiFi Orange Pi 3 has AP6256 WiFi/BT module. WiFi part of the module is called bcm43356 and can be used with the brcmfmac driver. The module is powered by the two always on regulators (not AXP805). WiFi uses a PG port with 1.8V voltage level signals. SoC needs to be configured so that it sets up an 1.8V input bias on this port. This is done by the pio driver by reading the vcc-pg-supply voltage. You'll need a fw_bcm43456c5_ag.bin firmware file and nvram.txt configuration that can be found in the Xulongs's repository for H6: https://github.com/orangepi-xunlong/OrangePiH6_external/tree/master/ap6256 Mainline brcmfmac driver expects the firmware and nvram at the following paths relative to the firmware directory: brcm/brcmfmac43456-sdio.bin brcm/brcmfmac43456-sdio.txt Signed-off-by: Ondrej Jirman Signed-off-by: Maxime Ripard --- .../dts/allwinner/sun50i-h6-orangepi-3.dts | 46 +++++++++++++++++++ 1 file changed, 46 insertions(+) diff --git a/arch/arm64/boot/dts/allwinner/sun50i-h6-orangepi-3.dts b/arch/arm64/boot/dts/allwinner/sun50i-h6-orangepi-3.dts index eda9d5f640b9..eb379cd402ac 100644 --- a/arch/arm64/boot/dts/allwinner/sun50i-h6-orangepi-3.dts +++ b/arch/arm64/boot/dts/allwinner/sun50i-h6-orangepi-3.dts @@ -56,6 +56,34 @@ regulator-max-microvolt = <5000000>; regulator-always-on; }; + + reg_vcc33_wifi: vcc33-wifi { + /* Always on 3.3V regulator for WiFi and BT */ + compatible = "regulator-fixed"; + regulator-name = "vcc33-wifi"; + regulator-min-microvolt = <3300000>; + regulator-max-microvolt = <3300000>; + regulator-always-on; + vin-supply = <®_vcc5v>; + }; + + reg_vcc_wifi_io: vcc-wifi-io { + /* Always on 1.8V/300mA regulator for WiFi and BT IO */ + compatible = "regulator-fixed"; + regulator-name = "vcc-wifi-io"; + regulator-min-microvolt = <1800000>; + regulator-max-microvolt = <1800000>; + regulator-always-on; + vin-supply = <®_vcc33_wifi>; + }; + + wifi_pwrseq: wifi-pwrseq { + compatible = "mmc-pwrseq-simple"; + clocks = <&rtc 1>; + clock-names = "ext_clock"; + reset-gpios = <&r_pio 1 3 GPIO_ACTIVE_LOW>; /* PM3 */ + post-power-on-delay-ms = <200>; + }; }; &cpu0 { @@ -91,6 +119,23 @@ status = "okay"; }; +&mmc1 { + vmmc-supply = <®_vcc33_wifi>; + vqmmc-supply = <®_vcc_wifi_io>; + mmc-pwrseq = <&wifi_pwrseq>; + bus-width = <4>; + non-removable; + status = "okay"; + + brcm: sdio-wifi@1 { + reg = <1>; + compatible = "brcm,bcm4329-fmac"; + interrupt-parent = <&r_pio>; + interrupts = <1 0 IRQ_TYPE_LEVEL_LOW>; /* PM0 */ + interrupt-names = "host-wake"; + }; +}; + &ohci0 { status = "okay"; }; @@ -102,6 +147,7 @@ &pio { vcc-pc-supply = <®_bldo2>; vcc-pd-supply = <®_cldo1>; + vcc-pg-supply = <®_vcc_wifi_io>; }; &r_i2c { -- 2.17.1
