This patch series adapts mmci driver to add support for stm32
sdmmc variant. stm32h7 SoC integrates the first revision of
stm32 sdmmc.
This series is composed of 3 parts:
-Prepare mmci driver to manage dma interfaces by adding property.
New mmci dma API is defined according to the legacy needs.
-Adapt mmci driver to dedicated constraints of stm32 sdmmc variant,
defined under some specific properties.
-Add stm32 sdmmc variant. As Internal DMA way satisfies data
transfer, the mmci driver hasn't been modified for pio_read/write.
Specific adds-ons to stm32 sdmmc:
+ registers
+ clk/power functions
+ idma interface
