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".

Whether the controller works in 8bit mode is not only dependent on the controller but also on the board having wired up 8 data lines, so put a capabilities field in platform data.

	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.

There are major differences in the clock tree of the S3C24xx family and the more recent CPUs of the S3C family. Keep the S3C24XX clock routines separate to avoid an ifdef hell.
