Subject: [PATCH 00/19] mmc: mmci: add stm32 sdmmc variant

From: Ludovic Barre <ludovic.barre@...com>

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

Ludovic Barre (19):
  mmc: mmci: regroup and define dma operations
  mmc: mmci: merge qcom dml feature into mmci dma
  mmc: mmci: add datactrl block size variant property
  mmc: mmci: expand startbiterr to irqmask and error check
  mmc: mmci: allow to overwrite clock/power procedure to specific
    variant
  mmc: mmci: add variant properties to define cpsm & cmdresp bits
  mmc: mmci: add variant property to define dpsm bit
  mmc: mmci: add variant property to define irq pio mask
  mmc: mmci: add variant property to write datactrl before command
  mmc: mmci: add variant property to allow remain data
  mmc: mmci: add variant property to check specific data constraint
  mmc: mmci: add variant property to request a reset
  mmc: mmci: send stop cmd if a data command fail
  mmc: mmci: add clock divider for stm32 sdmmc
  mmc: mmci: add stm32 sdmmc registers
  mmc: mmci: add DT bindings for STM32 sdmmc
  mmc: mmci: add stm32 sdmmc idma support
  mmc: mmci: add specific clk/pwr procedure for stm32 sdmmc
  mmc: mmci: add stm32 sdmmc variant
