The most common use cases for SDHI are: Soldered-on SD/MMC hardware: 1) SDIO module (for wifi for instance) Data IRQ + SDIO IRQ 2) eMMC chip Data IRQ External SD/MMC slot: 3) On hardware platforms with GPIO hotplug: Data IRQ + SDIO IRQ 4) On hardware platforms without GPIO hotplug: Hotplug IRQ + Data IRQ + SDIO IRQ Legacy support: 5) Common ISR All present IRQs To keep things simple and flexible I would prefer if the platform device could freely specify which interrupts to make use of. And still have the legacy behavior.
