Pull request overview
Adds an initial Zephyr SDHC driver for Alif SoCs and wires it up via devicetree and Kconfig so boards can use the new "alif,sdhc" compatible.
Changes:
- Introduce
alif,sdhcdevicetree binding and switch Alif DTS nodes to use it. - Add a new
sdhc_alifdriver implementation with DMA (ADMA2/SDMA) support and IRQ handling. - Register the driver in SDHC Kconfig/CMake so it builds when enabled.
