[PATCH V2 00/27] mmc: mmci: add sdmmc variant for stm32

[Ludovic Barre]

From: Ludovic Barre <ludovic.barre@xxxxxx>

The goal of this serie is to add support of sdmmc for stm32.
Be to able to add this new variant it is needed to do some changes in
mmci core:
-Internalize specific needs of legacy dmaengine.
-Create and setup dma_priv pointer
-Create generic callbacks which share some features (like cookie...)
and call specific needs

change v2:
-rename to mmci_prep/unprep_data
-rename specific dma engine structure to mmci_dmae_next/priv
-follow "_" recommandation
-remove dma prefixe of mmci_dmae_priv fields
