[PATCH v2 12/20] omap: hsmmc: allow board-specific settings of private mmc data

[Ohad Ben-Cohen]

Allow board-specific settings of private mmc data, in order to
allow embedded SDIO devices to communicate board-specific parameters
to the SDIO function driver (e.g., the external IRQ line of the wl1271).
