CONFIG_MMC_SPI: MMC/SD/SDIO over SPI

General informations

The Linux kernel configuration item CONFIG_MMC_SPI has multiple definitions:

MMC/SD/SDIO over SPI found in drivers/mmc/host/Kconfig

The configuration item CONFIG_MMC_SPI:

• prompt: MMC/SD/SDIO over SPI
• type: tristate
• depends on: CONFIG_SPI_MASTER
• defined in drivers/mmc/host/Kconfig
• found in Linux kernels: 2.6.28–2.6.39, 3.0–3.19, 4.0–4.20, 5.0–5.19, 6.0–6.8, 6.9-rc+HEAD
• modules built: mmc_spi, of_mmc_spi

Help text

Some systems access MMC/SD/SDIO cards using a SPI controller instead of using a "native" MMC/SD/SDIO controller. This has a disadvantage of being relatively high overhead, but a compensating advantage of working on many systems without dedicated MMC/SD/SDIO controllers.

If unsure, or if your system has no SPI master driver, say N.
