Subject: [PATCH v2 0/6] Update MMCI driver for STM32MP25

STM32MP25 is a new SoC from STMicroelectronics. The machine was
pushed by Alexandre [1] in his tree.
On this new SoC, the SDMMC peripheral, using PL18x/MMCI driver
has been updated to v3.
The driver has been updated to manage this new version, and the new
features it supports:
* FIFO size increased from 64B to 1kB
* IDMA size alignment/mask updated
* New block gap hardware flow control
* Delay block updated and dependent on SoC

This series was pushed on top of next branch in Ulf's mmc tree, as it
requires feedback clock update patch [2].

Changes in v2:
- update dt-bindings file (remove bootloader reference and use enum)

Yann Gautier (6):
  dt-bindings: mmc: mmci: Add st,stm32mp25-sdmmc2 compatible
  mmc: mmci: add stm32_idmabsize_align parameter
  mmc: mmci: Add support for sdmmc variant revision v3.0
  mmc: mmci: stm32: manage block gap hardware flow control
  mmc: mmci: stm32: prepare other delay block support
  mmc: mmci: stm32: add delay block support for STM32MP25
