Merge tag 'armsoc-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Pull ARM SoC platform updates from Olof Johansson:
 "SoC platform changes (arch/arm/mach-*). This merge window, the bulk is
  for a few platforms:

  Gemini:
   - Legacy platform that Linus Walleij has converted to multiplatform
     and DT, so a handful of various tweaks there, removal of some old
     stale support, etc.

  Atmel AT91:
   - Fixup of various power management related pieces
   - Move of SoC detection to a drivers/soc driver instead

  ST Micro STM32:
   - New SoC support: STM32H743

  TI platforms:
   - More driver support for Davinci (SATA in particular)
   - Removal of some old stale hwmod files (linkspace platform)

  Misc:
   - A couple of smaller patches for i.MX, sunxi, hisi"

+  Introduction
+  ------------
+        The STM32H743 is a Cortex-M7 MCU aimed at various applications.
+        It features:
+        - Cortex-M7 core running up to @400MHz
+        - 2MB internal flash, 1MBytes internal RAM
+        - FMC controller to connect SDRAM, NOR and NAND memories
+        - Dual mode QSPI
+        - SD/MMC/SDIO support
+        - Ethernet controller
+        - USB OTFG FS & HS controllers
+        - I2C, SPI, CAN busses support
+        - Several 16 & 32 bits general purpose timers
+        - Serial Audio interface
+        - LCD controller
+        - HDMI-CEC
+        - SPDIFRX
+        - DFSDM
+
+  Resources
+  ---------
+        Datasheet and reference manual are publicly available on ST website:
