From: Manivannan Sadhasivam <mani@xxxxxxxxxx> Stinger96 is a 96Boards IoT Extended edition board designed and manufactured by Shiratech solutions based on STM32MP1 SoC. Following are the features of this board: * 256MB DDR * 125MB NAND Flash * Onboard BG96 modem * 1x uSD * 2x USB (1 available as external connector and another connected to BG96) * 1x SPI * 1x PCM * 2x UART (apart from serial console) * 2x I2C (apart from one connected to PMIC) Following peripherals are tested and known to work: * BG96 modem * 1x I2C (LS-I2C0) * 1x SPI * 1x UART (LS-UART0) * USB (Only Gadget mode) * uSD More information about this board can be found in Shiratech website: https://www.shiratech-solutions.com/products/stinger96/ Signed-off-by: Manivannan Sadhasivam <mani@xxxxxxxxxx> --- arch/arm/boot/dts/Makefile | 1 + arch/arm/boot/dts/stm32mp157a-stinger96.dts | 12 + arch/arm/boot/dts/stm32mp157a-stinger96.dtsi | 342 +++++++++++++++++++ 3 files changed, 355 insertions(+) create mode 100644 arch/arm/boot/dts/stm32mp157a-stinger96.dts create mode 100644 arch/arm/boot/dts/stm32mp157a-stinger96.dtsi diff --git a/arch/arm/boot/dts/Makefile b/arch/arm/boot/dts/Makefile index f43467b02bcd..966b81dfffd6 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-stinger96.dtb \ stm32mp157c-dhcom-pdk2.dtb \ stm32mp157c-dk2.dtb \ stm32mp157c-ed1.dtb \ diff --git a/arch/arm/boot/dts/stm32mp157a-stinger96.dts b/arch/arm/boot/dts/stm32mp157a-stinger96.dts new file mode 100644 index 000000000000..249a53877512 --- /dev/null +++ b/arch/arm/boot/dts/stm32mp157a-stinger96.dts @@ -0,0 +1,12 @@ +// SPDX-License-Identifier: (GPL-2.0+ OR MIT) +/* + * Copyright (C) 2020 Manivannan Sadhasivam + */ + +/dts-v1/;
