Merge tag 'stm32-soc-for-v5.16-1' of git://git.kernel.org/pub/scm/linux/kernel/git/atorgue/stm32 into arm/soc
STM32 SoC for v5.16, round 1 Highlights: ---------- Add support of new STM32MP13 SoC which enhances current STM32 MPU family. It is mainly a derivative of STM32MP15 SoCs (one Cortex-A7 plus standard peripherals). The STM32MP13 SoC diversity is composed by: -STM32MP131: -core: 1*CA7, 17*TIMERS, 5*LPTIMERS, DMA/MDMA/DMAMUX -storage: 3*SDMCC, 1*QSPI, FMC -com: USB (OHCI/EHCI, OTG), 5*I2C, 5*SPI/I2S, 8*U(S)ART -audio: 2*SAI -network: 1*ETH(GMAC) -STM32MP133: STM32MP131 + 2*CAN, ETH2(GMAC), ADC1 -STM32MP135: STM32MP133 + DCMIPP, LTDC * tag 'stm32-soc-for-v5.16-1' of git://git.kernel.org/pub/scm/linux/kernel/git/atorgue/stm32: ARM: stm32: add initial support for STM32MP13 family docs: arm: stm32: introduce STM32MP13 SoCs Link: https://lore.kernel.org/r/0b6c9657-dcca-3bad-601f-610dfc81d9ae@foss.st.com Signed-off-by: Arnd Bergmann <arnd@arndb.de>

+===================
+
+Introduction
+------------
+
+The STM32MP131/STM32MP133/STM32MP135 are Cortex-A MPU aimed at various applications.
+They feature:
+
+- One Cortex-A7 application core
+- Standard memories interface support
+- Standard connectivity, widely inherited from the STM32 MCU family
+- Comprehensive security support
+
+More details:
+
+- Cortex-A7 core running up to @900MHz
+- FMC controller to connect SDRAM, NOR and NAND memories
+- QSPI
+- SD/MMC/SDIO support
+- 2*Ethernet controller
+- CAN
+- ADC/DAC
+- USB EHCI/OHCI controllers
+- USB OTG
+- I2C, SPI, CAN busses support
+- Several general purpose timers
+- Serial Audio interface
+- LCD controller
+- DCMIPP
+- SPDIFRX
+- DFSDM
