This device makes use of Stinger96 board by having it as a base board with one additional mezzanine on top. Following are the features exposed by this device in addition to the Stinger96 board: * WiFi/BT * CCS811 VOC sensor * 2x Digital microphones IM69D130 * 12x WS2812B LEDs Following peripherals are tested and known to work: * WiFi/BT * CCS811 More information about this device can be found in Shiratech website: https://www.shiratech-solutions.com/products/iot-box/ Signed-off-by: Manivannan Sadhasivam --- arch/arm/boot/dts/Makefile | 1 + arch/arm/boot/dts/stm32mp157a-iot-box.dts | 92 +++++++++++++++++++++++ 2 files changed, 93 insertions(+) create mode 100644 arch/arm/boot/dts/stm32mp157a-iot-box.dts diff --git a/arch/arm/boot/dts/Makefile b/arch/arm/boot/dts/Makefile index 966b81dfffd6..455ec6eb6303 100644 --- a/arch/arm/boot/dts/Makefile +++ b/arch/arm/boot/dts/Makefile @@ -1030,6 +1030,7 @@ dtb-$(CONFIG_ARCH_STM32) += \ stm32h743i-disco.dtb \ stm32mp157a-avenger96.dtb \ stm32mp157a-dk1.dtb \ + stm32mp157a-iot-box.dtb \ stm32mp157a-stinger96.dtb \ stm32mp157c-dhcom-pdk2.dtb \ stm32mp157c-dk2.dtb \ diff --git a/arch/arm/boot/dts/stm32mp157a-iot-box.dts b/arch/arm/boot/dts/stm32mp157a-iot-box.dts new file mode 100644 index 000000000000..fa1c006ce531 --- /dev/null +++ b/arch/arm/boot/dts/stm32mp157a-iot-box.dts @@ -0,0 +1,92 @@ +// SPDX-License-Identifier: (GPL-2.0+ OR MIT) +/* + * Copyright (C) 2020 Manivannan Sadhasivam + */ + +/dts-v1/; +#include "stm32mp157a-stinger96.dtsi" + +/ { + model = "Shiratech STM32MP157A IoT Box"; + compatible = "shiratech,stm32mp157a-iot-box", "st,stm32mp157"; + + wlan_pwr: regulator-wlan { + compatible = "regulator-fixed"; + + regulator-name = "wl-reg"; + regulator-min-microvolt = <3300000>; + regulator-max-microvolt = <3300000>; + + gpios = <&gpiog 3 GPIO_ACTIVE_HIGH>; + enable-active-high; + }; +}; + +&i2c2 { + ccs811@5b { + compatible = "ams,ccs811"; + reg = <0x5b>; + wakeup-gpios = <&gpioa 12 GPIO_ACTIVE_LOW>; + reset-gpios = <&gpioa 11 GPIO_ACTIVE_LOW>; + }; +}; + +&pinctrl { + /* + * Note: The SDMMC2 pins lack external pullups on data lines.
