For patches located in mach-stm32, for the next time I prefer that you
format commit header as following:
ARM: stm32: Add DMAv2 support on STM32MP157C.....
I don't see other issue, so don't resend for that, I will change it.
Regards
Alex

Series applied on stm32-next. As said before I modified commit header
for mach-stm32/Kconfig patch.
