Why This File Exists
Repeatable hardware-adapter layer. Deep compatibility for every driver is out of scope; this atlas records patterns, probe lifecycles, bus glue, IRQ/DMA usage, and links back to core abstractions.

comment "MMC/SD/SDIO Host Controller Drivers"
config MMC_DEBUG
bool "MMC host drivers debugging"
depends on MMC != n
help
This is an option for use by developers; most people should
say N here. This enables MMC host driver debugging. And further
added host drivers please don't invent their private macro for
debugging.
config MMC_SUNPLUS
tristate "Sunplus SP7021 MMC Controller"
depends on ARCH_SUNPLUS || COMPILE_TEST
help
If you say yes here, you will get support for eMMC host interface
on Sunplus SoCs.
If unsure, say N
config MMC_ARMMMCI
tristate "ARM AMBA Multimedia Card Interface support"
depends on ARM_AMBA
help
This selects the ARM(R) AMBA(R) PrimeCell Multimedia Card
Interface (PL180 and PL181) support. If you have an ARM(R)
platform with a Multimedia Card slot, say Y or M here.
If unsure, say N.
config MMC_QCOM_DML
bool "Qualcomm Data Mover for SD Card Controller"
depends on MMC_ARMMMCI && QCOM_BAM_DMA
default y
help
This selects the Qualcomm Data Mover lite/local on SD Card controller.
This option will enable the dma to work correctly, if you are using
Qcom SOCs and MMC, you would probably need this option to get DMA working.
if unsure, say N.
config MMC_STM32_SDMMC
bool "STMicroelectronics STM32 SDMMC Controller"
depends on MMC_ARMMMCI
default y
help
This selects the STMicroelectronics STM32 SDMMC host controller.
If you have a STM32 sdmmc host with internal DMA say Y here.
If unsure, say N.
config MMC_PXA
tristate "Intel PXA25x/26x/27x Multimedia Card Interface support"
depends on ARCH_PXA || COMPILE_TEST
help
This selects the Intel(R) PXA(R) Multimedia card Interface.
If you have a PXA(R) platform with a Multimedia Card slot,
say Y or M here.
If unsure, say N.
config MMC_SDHCI
tristate "Secure Digital Host Controller Interface support"
depends on HAS_DMA
help
Annotation
- Atlas domain: Driver Families / drivers/mmc.
- Implementation status: atlas-only.
Implementation Notes
- This generated page is the file-by-file coverage layer; curated subsystem chapters should link here when they synthesize a multi-file control flow.
- Core OS pages should be promoted from atlas-only to deep-reviewed when they explain data structures, invariants, locking, lifecycle, and C implementation snippets.
- Driver-family pages are intentionally pattern-oriented unless they are part of the selected PCIe/NVMe representative device path.
