Function Documentation

int __mmc_switch	(	struct mmc_card *	card,
		u8	set,
		u8	index,
		u8	value,
		unsigned int	timeout_ms,
		bool	use_busy_signal
	)

__mmc_switch - modify EXT_CSD register : the MMC card associated with the data transfer : cmd set values : EXT_CSD register index : value to program into EXT_CSD register : timeout (ms) for operation performed by register write, timeout of zero implies maximum possible timeout : use the busy signal as response type

Modifies the EXT_CSD register for selected card.
