It features: - Allwinner H2+ SoC - Single-chip (16-bit) 512MiB DDR3 DRAM - Ampak AP6212 Wi-Fi/Bluetooth module - MicroSD slot - Two MicroUSB Type-B ports (one can only be used to power the board and the other features OTG functionality) - Two keys, a reset and a GPIO-connected key. - HDMI Type-C (miniHDMI) connector connected to the HDMI part of H2+. - CSI connector to connect the camera sensor provided by Sinovoip. Signed-off-by: Icenowy Zheng --- Changes in v4: - Use SPDX license identifier. Changes in v3: - Add comments about Vbus problem in &usbphy node. Changes in v2: - Use high active SD card detect on the production batch. arch/arm/boot/dts/Makefile | 1 + .../boot/dts/sun8i-h2-plus-bananapi-m2-zero.dts | 126 +++++++++++++++++++++ 2 files changed, 127 insertions(+) create mode 100644 arch/arm/boot/dts/sun8i-h2-plus-bananapi-m2-zero.dts diff --git a/arch/arm/boot/dts/Makefile b/arch/arm/boot/dts/Makefile index ade7a38543dc..d5a17e6e8b0f 100644 --- a/arch/arm/boot/dts/Makefile +++ b/arch/arm/boot/dts/Makefile @@ -974,6 +974,7 @@ dtb-$(CONFIG_MACH_SUN8I) += \ sun8i-a83t-cubietruck-plus.dtb \ sun8i-a83t-tbs-a711.dtb \ sun8i-h2-plus-orangepi-r1.dtb \ + sun8i-h2-plus-bananapi-m2-zero.dtb \ sun8i-h2-plus-orangepi-zero.dtb \ sun8i-h3-bananapi-m2-plus.dtb \ sun8i-h3-beelink-x2.dtb \ diff --git a/arch/arm/boot/dts/sun8i-h2-plus-bananapi-m2-zero.dts b/arch/arm/boot/dts/sun8i-h2-plus-bananapi-m2-zero.dts new file mode 100644 index 000000000000..e2ee65a5bf92 --- /dev/null +++ b/arch/arm/boot/dts/sun8i-h2-plus-bananapi-m2-zero.dts @@ -0,0 +1,126 @@ +/* + * Copyright (C) 2017 Icenowy Zheng + * + * Based on sun8i-h3-bananapi-m2-plus.dts, which is: + * Copyright (C) 2016 Chen-Yu Tsai + * + * SPDX-License-Identifier: (GPL-2.0+ OR MIT) + */ + +/dts-v1/; +#include "sun8i-h3.dtsi" +#include "sunxi-common-regulators.dtsi" + +#include +#include + +/ { + model = "Banana Pi BPI-M2-Zero"; + compatible = "sinovoip,bpi-m2-zero", "allwinner,sun8i-h2-plus"; + + aliases { + serial0 = &uart0; + serial1 = &uart1; + }; + + chosen { + stdout-path = "serial0:115200n8"; + }; + + leds { + compatible = "gpio-leds"; + pinctrl-names = "default"; + + pwr_led { + label = "bananapi-m2-zero:red:pwr"; + gpios = <&r_pio 0 10 GPIO_ACTIVE_HIGH>; /* PL10 */ + default-state = "on"; + }; + }; + + gpio_keys { + compatible = "gpio-keys"; + pinctrl-names = "default"; + + sw4 { + label = "power"; + linux,code = ; + gpios = <&r_pio 0 3 GPIO_ACTIVE_LOW>; + }; + }; + + wifi_pwrseq: wifi_pwrseq { + compatible = "mmc-pwrseq-simple"; + pinctrl-names = "default"; + reset-gpios = <&r_pio 0 7 GPIO_ACTIVE_LOW>; /* PL7 */ + }; +}; + +&ehci0 { + status = "okay"; +}; + +&mmc0 { + pinctrl-names = "default"; + pinctrl-0 = <&mmc0_pins_a>; + vmmc-supply = <®_vcc3v3>; + bus-width = <4>; + /* + * On the production batch of this board the card detect GPIO is + * high active (card inserted), although on the early samples it's + * low active. + */ + cd-gpios = <&pio 5 6 GPIO_ACTIVE_HIGH>; /* PF6 */ + status = "okay"; +}; + +&mmc1 { + pinctrl-names = "default"; + pinctrl-0 = <&mmc1_pins_a>; + vmmc-supply = <®_vcc3v3>; + vqmmc-supply = <®_vcc3v3>; + mmc-pwrseq = <&wifi_pwrseq>; + bus-width = <4>; + non-removable; + status = "okay"; + + brcmf: wifi@1 { + reg = <1>; + compatible = "brcm,bcm4329-fmac"; + interrupt-parent = <&pio>; + interrupts = <6 10 IRQ_TYPE_LEVEL_LOW>; /* PG10 / EINT10 */ + interrupt-names = "host-wake"; + }; +}; + +&ohci0 { + status = "okay"; +}; + +&uart0 { + pinctrl-names = "default"; + pinctrl-0 = <&uart0_pins_a>; + status = "okay"; +}; + +&uart1 { + pinctrl-names = "default"; + pinctrl-0 = <&uart1_pins>, <&uart1_rts_cts_pins>; + status = "okay"; +}; + +&usb_otg { + dr_mode = "otg"; + status = "okay"; +}; + +&usbphy { + usb0_id_det-gpios = <&r_pio 0 6 GPIO_ACTIVE_HIGH>; /* PL6 */ + /* + * There're two micro-USB connectors, one is power-only and another is + * OTG.
