Subject[PATCH 00/14] Add MMCI support for STM32F SoCs family
From: Patrice Chotard <>

This series reworks patches submitted one year ago by Andrea Merello [1]
but without succeed to merged it.

STM32F4 and STM32F7 SoCs families embeds a variant of the ARM PrimeCell
PL18x SD host controller, for which the mmci driver exists.
This series adds support for these SoCs to the mmci driver.

As other variants, this one need some specific quirks, that this
series address.

This series has been tested on following boards :
_ stm32f429-eval
_ stm32f469-disco
_ stm32f746-eval
_ stm32f769-disco

DT update for stm32f7 pinctrl, stm32f746-eval and stm32f769-disco boards
will be sent later to avoid conflict with pending stm32f7 series [1] which
is not yet merged on kernel mainline.
