2012-02-29	d3fda04 Browse files » drivers/mci: fix read/write stalling ... If a read or write operation encounters an error, the card might stay in "recv" or "data" state, and never get back to "tran" state. In these cases, the host is required to send a CMD12 (end transmission) to switch the FSM of the card back to "tran" state, as described in MMC Specification, chapter "Data Transfer Mode".

2012-02-09	b795a73 Browse files » mci: Fix 8 bit mmc cards ... Currently we test the cards capabilities for being 8bit capable. This does not work since noone ever sets this bit. Unfortunately there is no bit to test 8bit capability, so we introduce a patch from the kernel which puts the mmc card into 8bit mode and tests whether it can succesfully read the ext_csd in this mode.

	113cb98 Browse files » mci: replace pr_debug with dev_dbg ... The mci layer uses pr_debug throughout. Use dev_dbg instead which is very useful when multiple cards are involved. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Sascha Hauer committed on 9 Feb 2012
	f27152c Browse files » mci: Use struct mci for internal argument passing ... The mci layer currently passes around a struct device_d for its internal use.

	4b8a61d Browse files » mci: fix high capacity detection ... Whether a card is high capacity is checked in sd_send_op_cond/mmc_send_op_cond.
