#1570714 — [PATCH 0/8] ADD STM32H743 MCU and STM32H743i-Eval board supports

This series adds basic support for STM32H743 MCU and stm32h743i-eval board.
With it, you can boot stm32h743i-eval board successfully.

For your information:

The STMicrolectornics's STM32H743 MCU has the following main features:
 - Cortex-M7 core running up to @400MHz
 - 2MB internal flash, about 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

#1570720 — [PATCH 6/8] ARM: stm32: Introduce MACH_STM32H743 flag

This patch introduces the MACH_STM32H743 to make possible to only select
STM32H743 pinctrl driver

By default, all the MACH_STM32Fxxx flags will be set with STM32 defconfig.

Patch 1 & 2 look fine to me.

Shall I just apply them and offer them on an immutable branch based
on v4.10 so you can pull that into ARM SoC if you want to get this in
for v4.11?

Thanks, but I think it is a bit late for this cycle. Indeed I'm close to 
send a second round for STM32 DT, but I don't plan to add STM32H7 
support. I prefere to let machine & DT patches in review.
Anyway, I 'll be happy if you take pinctrl & bindings parts in this 
cycle :).

Regards
Alex

Patch applied, renamed "bindings" to "definitions" in this commit
because it is not bindings.
