Subject: [PATCH v3 00/14] Add MMCI support for STM32F SoCs family

From: Patrice Chotard <patrice.chotard@...com>

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.

[2] https://patchwork.kernel.org/patch/10104447/

v3: _ patch 3: use variant->opendrain instead of host->variant->opendrain
    _ patch 4: exit from probe() if no pinctrl dt node are found
    _ previous patch 15: removed as already applied in pinctrl tree

v2: _ add Revievied-by, Acked-by in some patches
    _ replace bool by u32 for start_err and opendrain fields of struct variant_data
    _ split previous patch 3 in two parts, first patch clean the open drain bit code
      and second part add pinctrl pins management when no open drain bit is available.
    _ replace "pl180" by "PL180" in patch "mmc: mmci: Add STM32 variant"
