[PATCH 1/6] dt-bindings: mmc: mmci: Add st,stm32mp25-sdmmc2 compatible

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



For STM32MP25, we'll need to distinguish how is managed the delay block.
This is done through a new comptible dedicated for this SoC, as the
delay block registers are located in SYSCFG peripheral.
