Module mnemos_d1_core::drivers::smhc

Driver for the Allwinner D1’s SMHC peripheral.

The D1 contains three separate SD/MMC Host Controllers: SMHC0, SMHC1 and SMHC2.

• SMHC0 controls Secure Digital memory devices (SD cards)
• SMHC1 controls Secure Digital I/O devices (SDIO)
• SMHC2 controls MultiMedia Card devices (MMC)

Each SMHC also has an internal DMA controller that can be used for offloading the transfer and reception of large amounts of data to/from the device.
