| * mmc: dw_mmc: fix suspend/resume operationJaehoon Chung2011-03-171-2/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch is related to re-init processing on suspend/resume. When card is resuming, some register is reset. If card is removable, maybe controller should be rescan for card. But if assume card is non-removable, need to restore the old value at registers. We store the value of FIFOTH at probe time and then restore it in dw_mci_resume().

| | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds quirks and capabilities to platdata. Some cards don't use the CDn pin; in that case, we assume the card's inserted.

| * mmc: core: reset card voltage after power offUlf Hansson2011-03-171-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | At power off, reset OCR mask to be the highest possible voltage supported for the current mmc host. This solves the re-initialization during the power up sequence. The voltage may have been decreased due to the card accepts a lower voltage than the voltage used during the initialization sequence. We need to reset the voltage to by the host highest possible value since according to specification the initialization must always be done at high voltage.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | During redetection of a SDIO card, a request for a new card RCA was submitted to the card, but was then overwritten by the old RCA. This caused the card to be deselected instead of selected when using the incorrect RCA. This bug's been present since the "oldcard" handling was introduced in 2.6.32.
