ARM: dts: stm32: Add Stinger96 board support
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@kernel.org> Signed-off-by: Alexandre Torgue <alexandre.torgue@st.com>
